hetrick racing airshrouds

what kind of clutch system is that a little box on the handle bars, a short cable into the box and the another cable comes out and goes to the motor,, good eye on the a-arms i didnt see that.... those shrouds are interesting it would keep the exhaust heat off but it looks like it would trap engine heat in
