When it comes to maximizing performance and drivetrain safety, one of the most popular and effective upgrades is the Ultra-Light Billet Clutch Mod Kit.
This kit replaces the factory back-torque-limiting clutch assembly (commonly called a “slipper clutch”) with a precision-engineered billet unit. The result is a smoother, more controlled dead-stop launch—without the grab-and-jerk motion of the stock setup.
Beyond performance, the upgrade also reduces component wear caused by harsh launches. Factory slipper clutches often contribute to abnormal chain wear, sprocket damage, broken clutch baskets, and even bent output shafts. The Ultra-Light Billet Clutch Mod eliminates this violent jerking motion, protecting critical drivetrain parts.
Race-Proven Weight Savings
Every gram counts when chasing lower ETs. Weighing only 139 grams compared to the OEM’s 340 grams, this billet upgrade slashes nearly 60% of the rotating mass in the clutch area. That means less wasted energy spinning heavy stock parts—and more energy driving the bike forward, faster.
Smarter Launch Control
The kit also includes .180" clutch spring shim spacers for use with the stock springs. This provides a slight increase in clutch pressure, improving launches without creating drag strip chatter. The result: quicker 60-foots, smoother acceleration, and even improved top-end speed.
