Patrick racing would like to announce the introduction of the PR128!
The new 128 that redefines the definition of raw, unbridled power!
 
The Patrick Racing 128 is built on the same premise as all Patrick Racing motors; power through quality, efficiency, and technology. The 128 is based off of the very popular 4.25” bore motors and features only a 4½” stroke. Patrick Racing has remained true to our most basic philosophy of preserving shorter strokes and a computerized dynamic balance to keep your bike running smooth. As always, only the finest components in the industry are used in the construction Patrick Racing motors.
 
We are now taking orders for the new Patrick Racing 128 motor!
