A motorcycle exhibiting improved cornering clearance has its front and rear wheels mounted to a fixed frame portion via front and rear suspensions. A moveable frame portion including the motorcycle seat is moveably mounted to the fixed frame portion and moves under control of the rider further inside a corner during cornering in order to shift the effective center of gravity of the motorcycle further inside the corner and thus further increase the lean angle of the entire motorcycle. Movement is provided via a pivot, slidable shaft, or a pair of parallel linkages. The moveable frame portion may include only the motorcycle seat or may include the tank, seat, and entire motorcycle fairing.
