MOTOR ACCESSORIES
WE BUILT THE FIRST GENERATION OF THESE PARTS ON COMPUTERIZED EQUIPMENT LONG BEFORE OUR COMPETITORS COULD SPELL CNC. OVER THE YEARS WE HAVE CONTINUALLY IMPROVED AND UPGRADED OUR PRODUCT. WE DID IT FIRST, AND WE STILL DO IT BEST.

MOTOR PLATE and COUNTERSHAFT SUPPORT KITS:

(For Suzuki and Kawasaki)

The original heavy duty motorplate and countershaft support for high horsepower bikes running 15,' wheels. This design is incorporated into all Kosman Pro Stock rolling chassis The one-piece CNC machined outer plate ties the entire drive-side of the motor to the countershaft sprocket. The inner plate ties the rear of the assembly into the frame. The result is a totally rigid connection between motor, countershaft, and frame to eliminate flex under load. The countershaft sprocket rides on the ID of a large self-aligning bearing which allows the sprocket to turn freely under acceleration. This design eliminates the problem of bearing failure due to binding under load and also allows the sprocket nut to be re-torqued between rounds without disassembly. Complete kit includes seal, seal holder, and starter nut when ordered with sprocket.

Sprockets are subject to availability.

 

Includes:

  • alternator/bearing plate and bearing/frame plate
  • bearing hat with self-aligning bearing
