To suit: Suzuki RMZ250 07-15 Suzuki RMZ450 07-15Fitted to one side of the forks the launch control adds to the stability of the bike on race starts by lowering the ride height of the front end, locking it into position with the spring loaded launch mechanism. This allows the bike to sit level when the clutch is dropped and the rear suspension compacts reducing the tendency to rear-up therefore allowing the bike to travel in a straighter line. The clamp that fits on the fork leg upper has a hinge set up so you do not have to remove the fork leg for fitment. A stick on drilling template for the fork slider is provided in the packaging.
