13-17 SUZUKI RMZ450: Pro Circuit Launch Control The Pro Circuit Launch Control device will help compress the forks on a user's bike down a few inches from the normal position, when a rider is seated on the bike. At the start of a race, more load is being placed on the front end instead of the rear, lessening the chance of a wheelie out of the gate. The Pro Circuit Launch Control features a springless design that delivers positive engagement and consistent release. The newly-designed start trigger eases the setting and disengaging process, and helps to simplify installation of the entire kit. Every Pro Circuit Launch Control device is CNC-machined exclusively from aircraft-grade aluminum for a lightweight improvement to every racer's bike.
