Embodiment 1

[0052] The two-wheeled motor vehicle 1 shown in Fig. 1 is a small motorcycle (low-pedal type vehicle) having a foot resting portion for the occupant, that is, a low-pedal portion 2, and its front wheels 3 are pivotally supported on left and right front forks 4, each front The fork 4 is operably pivotally supported on a head pipe 7 at the upper front end of the vehicle frame 6 via a handle bar 5 , and a handle 8 for steering is attached to the upper part of the handle bar 5 . Here, the contact portion of the front wheel 3 (front wheel contact portion) is denoted by symbol FT in the figure.

[0053] The frame 6 is integrally combined with various steel materials by welding etc., and mainly consists of the lower frame 11 extending obliquely rearward and downward from the head pipe 7 , and the main frame above the engine 15 extending rearward from the lower part of the lower frame 11 and passing through the inner side of the low pedal part 2 12 and a seat frame 13 extending obliqu...

no. 2 example

[0087] In this second embodiment, only the form of the engine is different from the above-mentioned first embodiment, and other parts that are the same as those in the first embodiment are denoted by the same symbols and descriptions thereof are omitted.

[0088] As shown in FIG. 3 , the engine 15 which is the prime mover of the motorcycle 101 is, for example, a water-cooled four-stroke V-type twin-cylinder engine. The cylinder 117f and the rear engine 117r are erected substantially upward from the upper portion of the crankcase 116 . The transmission case 18 is connected to the rear of the crankcase 116 .

[0089] The radiator 39 is arranged in front of the front cylinder head 117fa, the air cleaner 40 is arranged above the radiator 39, and the intake pipes 142 branched and extended from the throttle body 41 connected to the rear of the air cleaner 40 are respectively It is connected to the intake ports on the upper part of the front cylinder head 117fa and the front part of...

Abstract

A main frame 12 extends from a front upper portion of an engine 15 in a vicinity of a low-floor part 2 to an upper part of a swing arm pivotably-supporting part 18a. A hindmost engine mount part C2 is provided on a rear portion of the main frame 12. A foremost engine mount part C1 is provided on a down frame 11. The foremost engine mount part C1 is located on the line L to connect the hindmost engine mount part C2 to a ground contact part FT of a front wheel 3 in side view of a vehicle.

Description

technical field [0001] The present invention relates to low-pedal vehicles such as scooter-type two-wheeled vehicles. Background technique [0002] Conventionally, in the above-mentioned low-pedal type vehicle, a low-pedal portion as a footrest portion for the occupant is provided between a handle for steering the front wheels and a seat for the occupant, and near the low-pedal portion, a An engine for driving the wheels is supported on the vehicle frame, and a swing arm for pivoting the rear wheels is pivotally supported at the rear of the engine (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 11-301559 [0004] In recent low-pedal vehicles, the displacement of the engine tends to increase, resulting in an increase in the size and weight of the engine and the vehicle frame. Therefore, the rigidity of the vehicle body must also be high. On the other hand, along with the increase of the driving force of the ...
