The air clutch was designed to give you an advantage in reaction times and consistent clutch control. The clutch lever is manually pulled in, a thumb button is pushed, holding the clutch lever in place. When you want to release the clutch lever, just push the button. Features include a clutch lever switch to operate your 2-step and a pro push-button to activate the air clutch. The Deluxe Air Clutch comes with a needle valve and adjustable clutch switch. This allows you to take total control of the clutch with adjustments for clutch lever release speed as well as adjustment for launch rev limiter release to clutch engagement. May be used with or without a delay timer.
