ABSTRACT:
A straddle vehicle comprises a single actuator that controls clutch engagement as well as gear shifting. The actuator can be connected to the clutch and the shiftable transmission with a rotating shaft. When an engine speed reaches or exceeds a preset value during an up-shift operation, an ECU or other controller reduces the engine output to facilitate a smooth gear shift.
