A Brock's Performance Clutch Mod is required for the ZX-14R to be launched smoothly from a dead stop! Brock’s Performance Clutch Mod disables the factory slipper clutch. This allows the rider to perform a smooth launch as opposed to the grab-n-jerk associated with trying to launch a stock machine from a dead stop.

This kit also includes heavy duty clutch springs and spacers to increase clutch pressure without causing chatter or a lack of top end speed. The shim adjustable spring tops allow you to fine tune your set-up and discover what works best for you. Our springs are manufactured from valve spring quality material, shot-peened and stress relieved specifically to handle the heat and stress of high power drag-style sport bike launches. A Clutch Shim Assortment Kit is also included for use with Brock’s Performance shim adjustable spring tops. This allows you to fine tune your clutch spring pressure for any application. The combinations are endless with a large assortment of shims and spacers to choose from.

We spared no expense to produce a clutch kit for your late model rocket, neither should you.
