摘要： A compression release mechanism including a camshaft, a cam provided on the camshaft and protruding outward in a radial direction of the camshaft, a lever, of which a portion is disposed in the camshaft, a support shaft supporting the lever such that the lever is swingable between a first position and a second position relative to the camshaft, and a spring attached to the camshaft, to urge the lever toward the first position. The lever includes a cam portion configured to protrude out from the camshaft with the lever at the first position, a centrifugal weight for moving the lever toward the second position in accordance with rotation of the camshaft, and an abutment portion configured to be in abutment with an inner peripheral surface of the camshaft with the lever at the first position, and be located away from the inner peripheral surface with the lever at the second position.

摘要： A control system for a straddled vehicle including an electric motor for driving the straddled vehicle, the electric motor being configured to generate a drive force and a regenerative brake force. The control system includes: a first operating member for controlling the drive force of the electric motor, a second operating member for reducing either the drive force or the regenerative brake force of the electric motor; a control device configured to control the drive force of the electric motor in accordance with an operation of the first operating member, and to reduce either the drive force or the regenerative brake force of the electric motor in accordance with an operation of the second operating member, and a load adjusting device adjusting an operating load acting on the second operating member based on an operating position of the second operating member.

摘要： An electric vehicle for a race, including a drive wheel, an electric motor linked to the drive wheel, a battery that supplies power to the electric motor, a remaining battery level detection unit that detects a remaining level of the battery, a control unit that controls the electric motor, and a throttle operator that is connected to the control unit and is operated by a rider when the rider adjusts an output of the electric motor. The control unit includes a motor control section that controls the output of the electric motor based on an amount of operation of the throttle operator, a power consumption rate calculation section that calculates a power consumption rate of the electric motor after a start of the race, and a travelable time estimation section that estimates a travelable time based on the remaining level and the power consumption rate.
