Extensively track-tested by Reedy factory drivers such as Ryan Maifield, Craig Drescher, Neil Cragg, and Richard Saxton, the VR-ST incorporates state-of-the-art features in a proven package.
The current 121VR engine has proven to be an economically priced, powerful race engine. The 121VR-ST (Special Tuned) takes performance to an entirely new level with the addition of a balanced ADLC-coated crankshaft, ceramic rear bearing, lightweight piston, and ADLC coated wrist pin. An ultra-lightweight heatsink head with "diamond cut" fins improves cooling while lowering the center of gravity.
The 121VR-ST is a race-proven engine that is capable of producing world-class power and fuel economy with a driver-friendly linear power band.
