EVR Slipper Clutch - BMW S1000RR/HP4/S1000R

The EVR slipper clutchis simply the BEST slipper clutch out there. It
will help eliminate rear-wheel chatter and reduce chassis instability
during aggressive downshifting. Slipper clutches reduce the
engine-braking effect the makes the rear wheel hop around under
heavy downshifting.

  • Highly effective engine to clutch-to-rear wheel power management
    system decreases unwanted engine braking and rear wheel drag
    when braking hard for a corner
  • Prevents damage to the engine and gearbox by reducing the
    mechanical stress caused by the back-torque of the engine and
    avoiding any chance of over-revving
  • Provides better clutch feel and smoother action
  • Uses original friction plates, drive plates, and basket
Brock's Performance Clutch Mod Kit

A Brock's Performance Clutch Mod is required for the BMW S 1000
RR 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 includes shim spacers to slightly increase clutch pressure
without causing chatter or a lack of top end speed.
Brock's Performance Heavy Duty Clutch Spring Kit

Complete kit to upgrade your clutch. 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. This
kit includes shim spacers to increase clutch spring pressure and
prolong clutch life. Helps increase E.T. and MPH.
