  • A Brock's Performance Clutch Mod is required for the ZX-10R 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.

    Attention: Although casual riding is generally unaffected after the installation of this product, some rear wheel ‘chirp, hop or chatter’ may be noticed, depending upon rider habits. All Brock’s Performance products are designed for Competition Use Only. 

Say good bye to the typical industry clutch spring. 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. Brock's new springs are guaranteed for millions of trouble-free (and SAG-free) cycles.

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