A frame structure for a motorcycle includes a main frame for supporting a front structure of the motorcycle, the main frame including a pair of main pipes extending rearward from a head pipe of the front structure; a pivot bracket including a metal plate, the pivot bracket connected to the main frame and including a rear cushion mounting portion and a swing arm mounting portion for swingably mounting a rear cushion and a swing arm. The main frame further includes: a pair of support pipes extending rearward from the head pipe for supporting the front structure; and a connecting portion jointly connected at a rear end of the pair of main pipes and the pair of support pipes for connecting to the pivot bracket. The rear cushion mounting portion is positioned forward of the connecting portion of the main frame when viewed from a side view of the motorcycle.

Frame structure for a motorcycle

A braking device of a saddle-ride type vehicle that can reduce a load acting on a joint is provided. A jointat a front-wheel brake output side which connects a metal pipe and a flexible brake hose is mounted on a body framevia a mount rubberunder a floating state.

A non-uniform load is prevented from acting on a cross member to reduce the weight of the cross member in a saddled vehicle. In the saddled vehicle has a vehicle body framefor suspending an engine, a swing armfor suspending a rear wheel WR freely swingably, pivot portionswhich are formed as a right-and-left pair, constitute a part of the vehicle body frameand pivotably support the swing arm, a lower cross memberfor joining the pivot portions, a rear cushionfor applying elastic force to the swing arm, a link mechanismfor joining the lower endA of the rear cushion, the swing armand the pivot portions, a link joint staywhich is formed at the rear side of the lower cross memberand joins the link mechanism, and a lower hungerthat is formed at the front side of the lower cross memberand fixes the engine, the link joint stayand the lower hungerare formed at the same position with respect to the vehicle width direction.

Saddled vehicle

A saddle-ride type vehicle with a swing arm swingably supported on a body frame. A shock absorber is connected to the body frame and the swing arm for applying a damping force. A shock absorber support member is suspended to the body frame in a vehicle width direction for supporting an upper end of the shock absorber. The shock absorber is supported on a central portion in the vehicle width direction of the shock absorber support member. The central portion in the vehicle width direction of the shock absorber support member is formed in a U-shape that is open at a lower side in a cross section taken along a longitudinal direction of the vehicle. An upper surface and a lower surface of the shock absorber support member are curved wherein a central portion lies above the end portion in the vehicle width direction.

Saddle-ride type vehicle

To enhance a degree of freedom in the shape and the design of a swing arm without being influenced by the variation of a part for supporting an exhaust muffler on the side of the swing arm and a part for coupling a rear cushion unit to the side of the swing arm in a compact vehicle, a cushion bracket coupled to a lower end of the rear cushion unit and a muffler bracket that supports the exhaust muffler are provided as separate elements from the swing arm and are attached to the swing arm.

Compact vehicle

An engine suspension device for a motorcycle can be increased in design flexibility and weight. An engine suspension device for a motorcycle has a suspension link provided between a body frame and an engine for pivotably supporting the engine. The suspension link includes a link body. Two pairs of right and left cylindrical members are provided at opposite ends of the link body and are connected to the body frame and the engine, respectively. The pairs of right and left cylindrical members are spaced apart from each other in the lateral direction of the motorcycle. The suspension link further includes a right connecting member for connecting the right cylindrical members and a left connecting member for connecting the left connecting members. The right and left connecting members are connected to each other by the link body.
