Item Description

Malossi 19 x 17 Variator Rollers in various weights. Click add to cart to see weight selections

If you have a 2015 or newer 3-valve engine on your Vespa Primavera or Sprint 150, Vespa 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 shacoking difference on these engines. The factory rollers weigh 14 grams and really limit the potential that's built into these motors.

If you have the 2014 and older Leader 125-150cc leader motors with stock variator we recommend 10 gram weights. The stock weight from the factory is 10 grams. We recommend going for 9.5 gram set with a cylinder kit OR a pipe, and 9 grams with both a cylinder kit and a pipe.
