Take the chatter out of your clutch and put consistency back into your passes. Brock’s Performance Clutch Cushion Kit transforms the Hayabusa clutch into a smooth, chatter-free system that saves you time, effort, and headaches. No more pre-oiling plates or wasting runs just to get things to settle in—this kit works right out of the gate.
Designed with Brock’s engineered clutch springs, the kit not only extends clutch life but also provides the smoothest, most predictable operation—especially in high-torque, big-displacement builds. For riders frustrated by the unpredictable action of the stock clutch, this isn’t a band-aid—it’s the mechanical cure.
