AFTERMARKET 19X17 ROLLERS 12.5G - SPRINT/PRIMA/FLY 150CC 3V

AFTERMARKET 19X17 ROLLERS 12.5GRAMS - SPRINT/PRIMAVERA **150CC 3V UPGRADE**

For the 2015+ 3V engine on your Primavera/Sprint 150, 946, or Fly 150, you will want these rollers in 12.5 grams for a significant power increase. As a stand alone upgrade, these make a shocking difference on these engines. The factory roller weights are very heavy, at 14 grams, and really limit the potential that's built into these motors.
