The G2 Quick Turn Throttle Tube will give your bike a throttle response boost just like it does for top motocross and Supercross riders like James Stewart, Grant Langston and Mike Lafferty to name a few. G2 made it as easy as possible to install by requiring no modifications. Simply remove your motorcycle's old throttle tube and install the Quick Turn. Constructed out of 6061 billet aluminum that provides an extremely durable and lightweight throttle tube. The center has been knurled for superior contact with the grip. The cam shape has a more aggressive curve to reduce the amount of movement required to open the throttle at max. Can be used for all types of racing with the removable end cap. The end cap can be installed for motocross and Supercross racing or removed to use hand guards.
