Abstract: 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.

Abstract: It is preferable to reduce an uncomfortable feeling arising from an abrupt driving force generated in an automatic starting clutch in an automatic clutch vehicle. When an automatic clutch operating device is about to automatically engage a starting clutch, a brake controller drives a brake actuator to forcibly actuate a brake device, thereby braking a driving wheel WR. Here, a brake pressure to be applied to the driving wheel WR can be set as a brake pressure such as to change an expected driving torque which is accompanied by an uncomfortable feeling in the absence of control by the brake controller into a norm driving torque which is not accompanied by the uncomfortable feeling, taking into account the clutch capacity and an engine control output.

Abstract: In a saddle-type vehicle, an engine is supported by a pivot shaft through insertion of the pivot shaft into a bracket part provided at a rear part of the engine. A center lower cross frame is so provided as to span a space between parts in left and right pivot plates on the lower side relative to the pivot shaft. The pivot shaft and the center lower cross frame are connected by a hanger member.
