'09 CRF 450R: The Motion Pro throttle assembly is a complete kit, from the carb/throttle body to the grips. After a pretty hard trip to the ground I noticed my throttle was sticking and further inspection showed a broken throttle tube and kinked pull side cable. Finding a complete kit with 4 different cam sizes made my day. After taking my time to route the cables and adjust them the cams can be switched out with minor adjustment on the topside cable adjusters. Sweet kit, from the cables & cams to the grips, I only wish motosport would carry the billet throttle tube for this kit.
