Fixed tank-mounted fasteners secure a motorcycle tank bag, protect the fuel cap, and let riders refuel by pivoting the bag aside.

A removable frame assembly opens engine access without sacrificing off-road rigidity, while cooling and modular foot wells cut weight and improve ergonomics.

Elastic fingers let a straddle-vehicle seat base conform to adjacent body structures during assembly, securing the frame mount without visible fasteners.

Interconnected tubes mimic a motorcycle frame to hold body panels in mounting positions and prevent scratches during service.

A motorcycle seat rail side wall features an outward bulge and inward flange to create internal volume for electrical components.

Adjustable locking mechanism secures saddle vehicle seats to frames.

Electrical component unit positions near center of gravity between fuel tank and air cleaner box.

A self-supporting hollow shell integrates the steering column, engine mounts, and suspension system into a single structural unit.

Guard frame redirects impact loads along fuel tank axis, preventing deformation risks and enabling larger capacity.

Integrating the canister mounting portion with the fuel tray eliminates costly metal stays, simplifying assembly while maintaining vibration isolation.

Segmented charge pipe passage with elastic tube prevents fuel flowout from tank during tilting, resolving reliability trade-offs.

Injection molded plastic halves form a rigid box section that houses electronics and eliminates separate air filter boxes or fuel tanks.

Segmented skid plate with bulging portions directs ram air to cool the engine while extended fuel tanks increase capacity without blocking airflow.

Fastening resin tank bent surfaces to frame components reduces monocoque rear frame weight while maintaining support reliability.

Longitudinal grooves on the upper surface suppress resonance vibrations and maintain capacity without lowering rigidity.

A partition wall isolates the generator from the fuel pipe on the engine rear side, preventing heat transfer that raises fuel temperature and reduces output.

Diverging main frame extensions support protruding tank stays, increasing fuel capacity while minimizing vibration transfer and simplifying assembly.

A motorcycle fuel tank uses a recessed portion to channel intake air directly to the air cleaner.

Segmenting the motorcycle tank cover into independent front, rear, and lower units allows damaged parts to be replaced without swapping the entire assembly.

Segmented wing member with inclined edges prevents deformation under airflow forces, enhancing rigidity and down force.

A press-molded aluminum fuel tank panel uses a recessed bent part to increase surface area and reduce wrinkles during forming.

Partition wall separates canister from accessory space, reducing interference and component count.

Mounting the fuel filter and pressure regulator on the fuel tank eliminates pipe disconnection during detachment, reducing fuel loss.

Segmenting the fixation into a removable jig and embedded portion resolves the trade-off between secure mounting strength and ease of recycling.

Overlapping skid and side guards eliminate gaps that let mud enter, protecting the fuel tank without adding weight.

Curved shrouds guide air to the engine, resolving the trade-off between airflow volume and structural stability at the fuel tank.

Swelling portions on the bracket body form a dedicated gap that allows throttle cables to pass through instead of wrapping around the bracket periphery.

Positioning the fuel tank between upper and lower link axes minimizes center of gravity shifts while preserving large capacity in tilting vehicles.

An integrated attaching member prevents welding holes in thin fuel tanks while reducing part count.

Merging the fuel tank into the frame creates a pyramidal structure that enhances torsional rigidity while reducing overall weight.

Offset bracket coupling portion connects down frame and engine, absorbing front-to-rear impacts while resisting twisting forces during cornering.
