Description

[0001] MOTORCYCLE WITH WINDSHIELD HAVING AN ADJUSTABLE POSITION DESCRIPTION

[0002] FIELD OF THE INVENTION

[0003] The present invention falls within the scope of manufacturing of saddle type motorcycles having two or three wheels. In particular, the invention relates to a motorcycle, preferably with two wheels, provided with a windshield whose position can be manually adjusted simply and quickly, even using only one hand.

[0004] PRIOR ART

[0005] As is known, many two or three-wheel motorcycles are normally provided with a front windshield supported by a structure directly or indirectly connected to the motorcycle frame. In general, the windshield has the function of protecting the rider while riding. In the case of road motorcycles, the windshield is also referred to with the term "deflector" or "windshielddeflector" o indicate the property of deflecting air, avoiding direct impact with the rider for the benefit of driving comfort, its safety and aerodynamic behaviour of the motorcycle. In some cases, the windshield can have a configuration and extension such as to prevent the rider from impact with small external objects, such as insects, debris, etc.

[0006] With respect to the structure that supports it, the windshield can have a fixed position or an adjustable position. This second type of windshield is particularly appreciated by riders, as it allows for greater customization of the motorcycle.

[0007] A first example of an adjustable position windshield is described in document GB733208. In this solution, the windshield is supported by two uprights fixed to a front bar of the vehicle. Each upright is provided with a plurality of notches in which a clamp connected to the windshield engages, in a reversible manner. By varying the engagement position of the clamps on the notches of the two uprights, the vertical position of the windshield relative to the front bar of the motorcycle is varied.

[0008] A conceptually similar solution is also described in DE 102005005681. In this case, the windshield support structure comprises a part defining two parallel tracks, each of which defining a recess in which a windshield holder element fixed in two points to the windshield itself is inserted. Each windshield holder element is provided with a fixing means which can be reversibly fixed in the hollow of the relative track in different fixing positions. Each fixing position establishes a corresponding position of the windshield relative to the support structure. A further example of a windshield device with adjustable position is described in DE102015106599. In this case a U-shaped windshield support frame is provided, to which the windshield is fastened in four points. Such a frame remains comprised between the support structure, integral with the motorcycle frame, and the windshield itself. More precisely, the U- shaped frame comprises two legs, each provided with an end portion slidingly inserted into a track defined on the support structure of the motorcycle. A crosspiece connects the two legs and supports, in the centreline, a first fixing element which reversibly engages in a second fixing element integral with the support structure. The second support element defines a plurality of pre-established fixing positions, each of which corresponds to a possible operating position of the windshield. The position is adjusted by exerting a manual pulling or pushing force on the transversal part of the windshield holder frame. Following such a pulling / pushing, the first fixing element releases from the second fixing element to subsequently re-fix thereto in a different pre-established position.

[0009] Another known solution is disclosed in US2002041107A1. In particular, in this document an adjustable windshield connected to the main frame of the motorcycle is disclosed.

[0010] Relative to the other solutions described above, that of DE10201506599 allows to perform an easier and relatively quicker adjustment due to the presence of the windshield holder frame. However, the solution of DE 10201506599 also has several disadvantages attributable precisely to the arrangement and use of the aforementioned frame.

[0011] The shape and position assumed by this frame leads the windshield to be placed at a certain distance from the support structure. It follows that, while driving, the frontal air also spreads into the space / gap between the support structure and the windshield, causing vibrations and therefore instability on the windshield itself. In addition to this, the relatively complex shape of the windshield holder frame has a negative impact on manufacturing costs. Furthermore, if on the one hand the windshield holder element allows the position of the windshield to be manually adjusted, on the other hand such an adjustment is not easy and requires the use of both hands to complete the operation.

[0012] Following the considerations above, the need emerges for a new technical solution which makes the adjustment of the windshield position even faster and more reliable than what is currently permitted by the known solutions.

[0013] SUMMARY

[0014] The main task of the present invention is to provide a motorcycle which allows the above- mentioned drawbacks to be resolved or at least mitigated.

[0058] DETAILED DESCRIPTION

[0059] With reference to the aforementioned figures, the present invention therefore relates to a two- or three-wheeled motorcycle comprising a windshield 3 having an adjustable position. Figure l is a side view of a two-wheeled road motorcycle 1 according to the present invention. Such a motorcycle 1 comprises a frame 102 which supports a saddle 103, a tank 104 and a thermal engine 105. A rear wheel 101B is driving, as it is connected to the thermal engine 105 via a chain transmission, while a front wheel 101 A is steering by means of the handlebar 107 which can be rotated inside a steering tube 109.

[0060] In any case, the shape of the frame 102, the handlebar 107, the wheel suspensions and the propulsion mode of the motorcycle (thermal, electric or hybrid) are not relevant in relation to the present invention. In this regard, the motorcycle 1 could also be of the three-wheeled type with two rolling and steering front wheels and a driving rear wheel.

[0061] For the purposes of the present invention, the expression "longitudinal direction" or "front-to- back direction” means a direction parallel to the travel direction of the motorcycle 1 and orthogonal to the rotation axis M of the driving wheel 10 IB, while the expression "transversal direction" or "right-left" direction is intended to indicate a direction substantially orthogonal to the longitudinal direction and parallel to the rotation axis M of the driving wheel 101B. Finally, the expression “normal direction ” or “up-down ” direction indicates a direction orthogonal to the longitudinal direction and the transversal direction.

[0062] The figures comprise reference Cartesian axes indicating the front-back direction F-B, the up- down direction U-D and the right-left direction R-L defined above. Therefore, the terms “longitudinally or longitudinal”, the terms “transversally or transversal" and the terms “normally or normal” refer respectively to the longitudinal direction, i.e., front-back F-B, to the transversal direction, i.e., right-left R-L, and to the normal direction, i.e., up-down U-D. The terms “front”, “left” and “above” refer to the directions indicated by the arrows of the half-lines F, L and U visible in the figures. The terms "rear", "right" and "below" instead indicate directions opposite those indicated by the arrows of the half-lines B, R and D.

[0063] In figures 3 and 5, a longitudinal centreline plane PL of the motorcycle 1 is drawn. Such a plane PL extends mainly in the longitudinal direction F-B of the motorcycle 1 and is orthogonal to the transversal direction R-L, i.e., to the rotation axis M of the driving wheel 101B, i.e., vertical to the plane PO on which the motorcycle 1 rests.

[0064] For the purposes of the present invention, the expression "motorcycle considered to be straightwheeled" means a condition whereby the two wheels 101 A, 102B are substantially coplanar, as for example in the condition shown in Figure 1.

[0065] The motorcycle 1 comprises a front assembly of components (indicated with the reference 2 in Figure 1 ) placed in front of the steering tube 109. Such a front assembly 2 is connected to the handlebar 107, preferably through a connection frame 108, so as to be rotatable together therewith around the rotation axis 400 (indicated in Figure 1) configured by the steering tube 109. In the embodiment with reference to figures 8, 9, and 10, the front assembly 2 comprises a windshield 3, a front light 200, the direction lights 250 (figures 2 and 3) and an instrument panel 260, i.e., part of the control instrumentation of the motorcycle 1.

[0066] In particular, said front assembly 2 comprises an interface structure 5 shaped to allow the assembly of the windshield 3 with respect to the other components of the front group 2. The interface structure 5 preferably extends above the front light 200. As visible, for example, in Figures 2 and 3, even more preferably the lower edge 31 of the windshield 3 and / or the lower edge 51 of the interface structure 5 have a profile geometrically similar to the upper profile 201 of the front headlight 200 that is also integral with the handlebar 107 (see Figure 3). In particular, the front light 200 is shaped like a pair of circular elements which are connected to each other in a centreline position to form a connection bridge. At the connection bridge there is a shaped element 222 (indicated in figures 2 and 3) which extends transversally - which represents a logo - and is positioned centrally to the two circular elements. Preferably, the central shaped element 222 is a daytime running light DRL.

[0067] The motorcycle 1 according to the invention comprises an adjustment assembly 6 for adjusting the position of the windshield 3 relative to the interface structure 5 (hereinafter also indicated only with the term structure 5). The adjustment assembly 6 comprises a first fixing element 11 slidingly coupled to a first guide 21 integral with the structure 5 and a second fixing element

[0068] 12 slidingly coupled with a second guide 22 also integral with the interface structure 5. According to the invention, the adjustment assembly 6 further comprises a third fixing element

[0069] 13 which reversibly engages an adjusting element 23 (see Figure 5) integral with the structure 5, where such an adjusting element 23 defines a plurality of fixing positions for the third fixing element 13 so as to vary the position of the windshield 3. In practice, each fixing position establishes a corresponding pre-established position for the windshield 3 relative to the structure 5.

[0070] According to the present invention, the three fixing elements 11, 12, 13 mentioned above are connected to each other via the windshield 3 and support the windshield itself with respect to the interface structure 5. In other words, according to the invention, the windshield 3 is supported, in an adjustable manner, with respect to the interface structure 5 by means of the three fixing elements 11, 12, 13 without the interposition of other elements having this purpose. Figures 2 and 3 show the windshield 3 in two different positions with respect to the structure 5. In particular, there is a first position corresponding to a completely lowered condition of the windshield 3 (Figure 2) and a second position corresponding to a completely raised condition of the windshield 3 (Figure 3). In other words, the first position of the windshield 3 is the one whereby, in the direction U-D, the lower edge 31 is near the front light 200 (Figure 2), while the second position of the windshield 3 is the one whereby the lower edge 31 is spaced from the front light 200 (Figure 3).

[0071] In terms of adjustment, those just described are the two extreme positions which can be occupied by the windshield 3 with respect to the front light 200 and therefore with respect to the structure 5. Preferably, the adjusting element 23 is configured so as to establish at least one, preferably a plurality, of intermediate positions between the first position and the second position defined above. In this regard, in the solution shown in the figures, the third adjusting element 23 is configured so as to establish a total of 5 possible adjustment positions of the windshield 3 with respect to the structure 5, and therefore three possible intermediate positions ( i.e., three different possible heights with respect to the front light 200) between the two extreme positions defined above. In accordance with a possible embodiment, shown in the figures, the adjustment assembly comprises a displacement handle 8 connected, directly or indirectly, to the third fixing element 13 to vary the fixing position thereof to the adjusting element 23. The term "directly" is intended to indicate a condition whereby at least one portion of the displacement handle 8 is connected to at least one portion of the third fixing element 13 (solution shown in the figures). The term "indirectly "is intended to indicate a condition whereby the transmission of the traction or thrust force from the displacement handle 8 to the fixing element 13 is allowed by another element / component. In this regard, in a possible embodiment, not shown in the figures, the displacement handle 8 could be connected only to the windshield 3. In fact, a pulling or pushing action on the windshield 3 is transferred to the three fixing elements 11, 12, 13 to which the windshield 3 itself is integral.

[0072] Figures 4 and 5 essentially correspond to Figures 2 and 3, but differ from these in that the windshield 3 is drawn transparent so as to show the arrangement of the fixing elements 11, 12, 13 and the respective components (first seat 21, second seat 22, adjusting element 23) integral with structure 5 to which they are coupled. The first fixing element 11 and the second fixing element 12 are connected to the windshield 3 so as to be symmetrical relative to the longitudinal plane PL defined above. The third fixing element 13 is connected to the windshield 3 in a central position, i.e., at the longitudinal plane PL, and above the other fixing elements 11, 12. It follows that the fixing elements 11, 12, 13 are substantially arranged in an isosceles triangle relative to a frontal observation plane (i.e., defined by the directions R-L and U-D), wherein the symmetry plane of such a triangle coincides with the longitudinal plane PL.

[0073] The components (first seat 21, second seat 22, adjusting element 23 ) of the adjustment assembly 6 integral with the structure 5 are arranged in a manner conforming with the fixing elements 11, 12, 13. Therefore, the first seat 21 and the second seat 22 are arranged symmetrically relative to the longitudinal plane PL, while the adjusting element 23 is arranged centrally near the same longitudinal plane PL and above the two seats 21, 22.

[0074] Figures 8, 9 and 10 show partial sections, at different depths along the direction R-L, of the front part of the motorcycle 1 with the windshield 3 in the first position defined above (windshield completely lowered). More precisely, Figure 8 shows a sectional view of the coupling between the third fixing element 13 and the adjusting element 23, wherein such a section is traced along a plane coinciding with the longitudinal plane PL. Figure 9 shows a sectional view of the connection of the displacement handle 8 (hereinafter also referred to only as handle 8) to the windshield 3, wherein such a section is also traced along a plane coinciding with the longitudinal plane PL. Figure 10 shows a sectional view of the coupling between the first fixing element 11 and the first seat 21, wherein such a section is traced according to a section plane parallel, but not coinciding, to the longitudinal plane PL. Figures 11, 12, 13 are partial sectional views, corresponding respectively to those of Figures 8, 9 and 10, wherein the windshield 3 is however shown in the second position defined above (windshield completely raised).

[0075] According to a preferred embodiment, each of the guides 21, 22 is defined by a rectilinear groove defined through the structure 5. More precisely, such a groove extends between an outer side 5A and an inner side 5B, opposite said outer side 5A, of the structure 5 (see Figure 15). Outer side 5A is intended as that facing the windshield 3, while inner side 5B is that substantially facing the handlebar 107 and / or towards the steering tube 109 of the motorcycle 1. The grooves defining the two guides 21, 22 are configured so as to define parallel sliding directions for the relative fixing elements 11, 12.

[0076] According to a preferred embodiment, the first fixing element 11 and the second fixing element 12 have the same shape. Reference is made below to the first fixing element 11, and therefore to the first seat 21, but the following considerations are to be considered valid also for the second fixing element 12 and the relative second seat 22.

[0077] The first fixing element 11 comprises a first portion 111 integral with the windshield 3, where such a first portion 111 emerges with respect to the outer side 5 A of the structure 5 (see Figure 15). The first fixing element 11 also comprises a second portion 112 integral with the first portion 111 and which emerges with respect to the inner side 5B of the structure 5. The two portions 111, 112 are connected by a third portion 113 which traverses the first seat 21.

[0078] The first fixing element 11 also comprises an elastic thrust means 115 which acts on the second portion 112, exerting a force as a result of which the windshield 3 is forced against the outer side 5 A of the structure 5. To this end, the elastic thrust means 115 is preferably defined by a spring, arranged on the inner side 5B of the structure 5, which exerts a traction force on the second portion 112 facing inwards, i.e., in the direction of the handlebar 107. As a result of the union between the portions 111, 112, 113 of the first fixing element, such a force also acts on the first portion 111 and therefore on the windshield 3 integral therewith.

[0079] The detailed view of Figure 15 shows a preferred embodiment of the first fixing element 11 which comprises a first pin 110A connected near a first end 129 thereof to the windshield 3 by means of an interface ring 116; preferably, a mushroom bushing 117 is positioned between the end 129 of the first pin 110A and the interface ring 116. To connect to the windshield 3, the first pin 110A emerges with respect to the outer side 5A of the structure 5, together with the interface ring 116 and the mushroom bushing 117. The first fixing element 11 also comprises a second pin HOB which emerges, at least partially with respect to the inner side 5B of the structure 5. Said a second pin HOB is coaxially connected to the first pin 110A. The two pins 110A, HOB can be connected through a thread. The first fixing element 11 also comprises a hollow element 118 (on which the interface ring 116 rests) which rests on the outer side 5 A of the structure 5 with a first part 118A thereof. The hollow element 118 is internally traversed by the first pin 110A and / or by the second pin HOB. The hollow element 118 comprises a second portion 118B which traverses the rectilinear groove defining the first guide 21.

[0080] Again with reference to figure 15, said elastic means 115 of the first fixing element 11 is a spring coaxial to the second pin 110B and which rests on the inner side 5B of the structure 5. Such a spring acts, directly or indirectly, on one end 119 of the second pin HOB so as to push it inwards, i.e., moving it away from said inner side 5B. Due to the connection with the first pin 110A, the thrust on the second pin HOB keeps the interface ring 116 stably against the first portion 118A of the hollow element 118. Consequently, the windshield 3 is kept in a stable position with respect to the structure 5.

[0081] In the solution in Figure 15, the spring acts on a washer 123 arranged near the end 119 of the second pin HOB. Therefore, the elastic force is transferred indirectly to the end 119 of the second pin 11 OB through such a washer 123. Alternatively, by suitably configuring such an end 119, the spring could act directly thereon.

[0082] According to a preferred embodiment, visible in particular in Figure 16, the adjusting element 23, to which the third fixing element 13 fixes, is defined by a shaped groove extending between the outer side 5A and the inner side 5B of the structure 5. With reference again to Figure 16, the third fixing element 13 comprises a first portion 131 and a second portion 132 that emerge respectively from the outer side 5 A and from the inner side 5B of the structure 5. These two portions 131, 132 are connected by a third portion 133 arranged inside said shaped groove (hereinafter also indicated with the reference 23). The third fixing element 13 also comprises an elastic means which acts on the second portion 132, exerting a force as a result of which it is pushed towards the outer side 5 A of the structure 5. It is observed that the principle of action of the elastic means envisaged for the third fixing element 13 is substantially analogous to that of the elastic means envisaged for the other two fixing elements 11, 12 described above. In practice, for all three fixing elements 11, 12, 13 of the adjustment assembly 6, the force exerted by the respective elastic means 115, 135 constantly keeps the windshield 3 in the fixing position established through the adjusting element 23. Always with reference to Figure 16, according to a preferred embodiment thereof, the third fixing element 13 comprises a first pin 130A connected at a first end 139 thereof to the windshield 3 through an interface ring 136. Preferably, a mushroom bushing 137 is envisaged between the interface ring 136 and said end 139. The first pin BOA emerges frontally from the outer side 5A of the structure 5. A second pin BOB is connected coaxially to the first pin BOA and emerges rearward with respect to the inner side 5B of the structure 5. Preferably, the two pins BOA, BOB are connected axially through a threaded coupling.

[0083] The third fixing element 13 further comprises at least one hollow element 138 comprising a first portion 138A (or coupling portion 138A) which removably couples to a seat 24 defined by a part 23" of the shaped groove 23. A second portion 138B of the hollow element 138 traverses another part 23' of said shaped groove 23 and is in turn internally traversed by the first pin BOA and / or by the second pin BOB. The hollow element 138 comprises a third portion 138C on which the interface ring 136 to which the windshield 3 is connected rests. This third portion 138C extends from the first portion 138A whereby the latter is comprised between the second portion 138B and said third portion 138C.

[0084] The elastic means 135 of the third fixing element 13 comprises a spring (hereinafter referred to as spring 135) that is coaxial with the pins BOA, BOB. Such a spring 135 rests, directly or indirectly, on the inner side 5B of the structure 5. In the solution shown in figure 16, a bushing

[0085] 143 is envisaged which is partially inserted in a portion 23' of the shaped groove 23, wherein such a bushing 143 is internally traversed by the second portion 138B of the hollow element 138 and comprises an edge portion resting on the inner side 5B of the structure 5 and on which said spring 135 rests. With a second end thereof opposite the first, the spring 135 acts on a stop

[0086] 144 that is integral with the second pin BOB near its end 149. Therefore, the spring 135 acts indirectly on the second pin BOB by means of the stop 144.

[0087] Always with reference to Figure 16, the first portion 131 of the third fixing element 13 is defined by the first pin BOA, by the interface ring 136, by the mushroom bushing 139, by the third portion 138C and partially by the first portion 138A of the hollow element 138. Instead, the second portion 132 of the third fixing element 13 is partially defined by the second pin BOB, by the stop 144, partially by the second portion 138B of the hollow element 138 and partially by the bushing 143.

[0088] With reference to Figures 7 and 16, according to a possible embodiment, the shaped groove 23 defining the adjusting element 23 comprises a first part 23' with parallel and straight sides extending from the inner side 5B of the structure 5 towards the outer side. The shaped groove 23 also comprises a second part 23" adjacent to said first part 23' and facing the windshield 3. The second part 23" defines a plurality of seats 24 in each of which the coupling portion 138A of the hollow element 138 of the third fixing element 13 can be inserted. Each of these seats 24 therefore defines a possible coupling position for the third fixing element 13 with the shaped groove, i.e., a specific fixing position for the windshield 3. With reference to figure 7 it can be observed that in the case illustrated, the second part 23" has five seats 24 and therefore defines five possible use / fixing positions for the windshield 3.

[0089] With reference again to Figure 7, a throat 24A is defined between two adjacent seats 24, configured so as to cause the coupling portion 138A of the hollow element 138 to exit from the seat 24 following a pulling or pushing action exerted (directly or indirectly) on the third fixing element 13. In other words, under said pulling or pushing action, due to the effect of such a throat 24A, the first portion 138A of the hollow element 138 decouples from the seat 24 in which it is inserted so as to subsequently recouple with / insert into another seat 24 of the shaped groove 23 when said pulling / pushing action ceases.

[0090] Figures 17 and 18 are respectively a further sectional view and a relative enlargement of the third fixing element 13 and of the adjusting element 23 during the variation of the fixing position. In particular, in the condition shown in Figure 18 the third fixing element 13 is decoupled from the adjusting element 23. Indeed, the coupling portion 138A of the hollow element 138 of the hollow element 138 is removed from each of the seats 24 and emerges completely outside the shaped groove. It can be noted that following such a removal, the windshield 3 moves away from the structure 5. This determines the temporary compression of the corresponding springs 115, 135 of the fixing elements 11, 12, 13 which constantly push the windshield 3 towards the structure 5. Therefore, even during the adjusting step (variation of the fixing position), the windshield 3 remains firmly constrained to the structure 5 through the three fixing elements 11, 12, 13.

[0091] In accordance with a preferred embodiment, the handle 8 comprises a connection portion 8B through which it is fixed to the third fixing element 13. The displacement handle 8 is also fixed to the windshield 3 through at least one fixing element 41. Preferably, the handle 8 is fixed to the windshield 3 by means of two connecting elements 41 arranged above the third fixing element 13, where said two connecting elements 41 are arranged symmetrically with respect to a longitudinal plane PL of the motorcycle 1 considered to be straight-wheeled.

[0092] With reference to Figures 6, 7 and 14, the handle 8 preferably comprises a front portion 81 in a position substantially facing the windshield 3 and a rear portion 82 which is inclined with respect to the front portion 81 and which extends above the same front portion 81. The rear portion 82 is therefore also inclined with respect to the windshield 3 and is configured so as to be graspable by a rider. As better described below, by acting on the rear portion 82 of the handle 8, the rider exerts a pulling or pushing action following which the position of the windshield 3 with respect to the structure 5 is varied.

[0093] In the embodiment shown in the figures, the front portion 81 has a V shape, where the part 8B of the handle 8 connected to the third fixing element 13 is defined at the vertex of such a V. The rear portion 82 instead has a substantially U shape where each leg 82A of the U is connected to a corresponding leg 81 A of the front portion 81. With particular reference to figures 6 and 7, the two connecting elements 41 that connect the handle 8 to the windshield 3 are each arranged at a point in which a leg 82A of the rear U-shaped portion connects to a leg 81 A of the front V- shaped portion.

[0094] As already indicated above, figures 2, 4, 8-10 show the windshield 3 completely lowered, i.e., in the first fixing position closest to the front light 200. Instead, figures 3-5, 11-13 show the same windshield 3 in the second fixing position farthest from the front light 200. With reference to Figure 4, in the first fixing position the first fixing element 11 and the second fixing element 12 are positioned substantially at the lower end of the corresponding guide 21, 22. The third fixing element 13 is engaged with the adjusting element 23 in the first fixing position defined near the lower end 23C (indicated in Figure 5) of the shaped groove. More precisely, the coupling portion 138A of the hollow element 138 of the third fixing element is inserted into a first seat 24' (indicated in Figure 7) envisaged in the second part 23" of the shaped groove. For all three fixing elements 11, 12, 13, the relative elastic means 115, 135 act so as to constantly push the windshield 3 towards the interface structure 5.

[0095] To vary the position of the windshield 3, starting from the first fixing position, the rider grips the rear portion 82 of the handle 8 and applies a traction force F ( indicated in Figure 10) which acts directly on the third fixing element 13. Following such a force, the hollow element 138 of the third fixing element 13 (in particular the coupling portion 138A thereof) decouples from the first seat 24 of the shaped groove 23 due to the effect of a corresponding throat 24A envisaged in the second part 23’ ’ of the groove itself. In this condition (visible in the sectional view of Figure 18), the hollow element 138, and consequently the entire third fixing element 13, is free to move relative to the adjusting element 23 (i.e., relative to the shaped groove 23) up to when the traction force ceases.

[0096] The windshield 3 moves integrally with the third fixing element 13 as a result of the constraint existing between the two components (windshield 3 and third fixing element 13). At the same time, the other two fixing elements 11, 12 also move integrally with the third fixing element 13 as they are connected to the latter precisely through the windshield 3. When the rider interrupts the traction on the handle 8, the coupling portion 138A of the hollow element 138 of the third fixing element 13 can couple in another seat 24 of the shaped groove 23 reached precisely as a result of said traction. If, for example, the rider intends to adjust the windshield 3 at the completely raised position, the traction applied to the handle 8 will be such as to move the third fixing element 13 close to the upper end of the shaped groove 23, i.e., until it allows to the coupling portion 138 of the hollow element 138 to couple with the seat 24 of the groove 23 farthest from the front light 200 below.

[0097] To move the windshield 3 from a higher fixing attachment position (like the one in figures 11 to 13) to a lower fixing position (as in figures 8 to 10), the rider will push downwards, in the direction indicated by the arrow Fl in Figure 13.

[0098] It should be noted that in a further embodiment not shown in the figures, the handle 8 may not be constrained to the windshield, being able to be slidingly coupled to the structure. In other words, the handle 8, although remaining directly connected to a portion of the third fixing element 13, may not have any connection point to the windshield 3.

[0099] The motorcycle 1 according to the invention allows the intended tasks and objects to be fully accomplished. In particular, the adjustment assembly of the windshield position allows to quickly and effectively change the position of the windshield. In this regard, such an adjustment can be carried out by a rider even using only one hand, therefore even with the motorcycle in motion.
