Product Details


This Stage III kit has been developed for the rider looking for a solid “seat of the pants” increase you can feel every time you roll on the throttle.

 Delivers increased throttle response throughout the entire RPM range
 Produces flexible roll-on passing power without a required downshift
 Delivers excellent stop-light to freeway speed on-ramp acceleration
 Retains Original Equipment Factory Warranty
 Includes 4.155" Big Bore Bolt-On Cylinders, Forged 11.0:1 High Compression Pistons and Rings, SE8-447 Torque Cam, High Capacity Tappets, High Performance Cam Bearing, Stage III Timer Cover & Insert
