Brock's Ultra-Light Billet Clutch Mod Kit Hayabusa (99-20), B-King (08-11) TL1000R (98-03)

Ultra-Light Billet Clutch Mod Kit for Suzuki Hayabusa (1999–2020), B-King (2008–2011), and TL1000R (1998–2003)

The Ultra-Light Billet Clutch Mod is the go-to upgrade for riders seeking smoother launches, better driveline protection, and faster acceleration. Replacing the factory back-torque limiter (slipper clutch), this billet aluminum mod eliminates the jerky "grab and jerk" behavior, providing a smoother, more efficient launch — whether on the street or drag strip.

Key Benefits:

• Eliminates bucking during dead stop launches

• Reduces drivetrain wear and protects chains and sprockets

• Promotes smoother clutch operation and longer clutch life

• 60% lighter than OEM clutch assembly (139g vs. 340g)

• Made from billet 7075 aluminum with military spec hard coat

• Increases lever pressure by only 10%

• Includes .180” clutch spring shim spacers

• No core charge or OEM exchange required

By reducing rotating mass, more energy is transferred into forward motion — meaning quicker acceleration and lower ETs. Tested on the world's highest horsepower Hayabusas, this mod is engineered for performance.
