Eliminate "flat spots" and unlock the true potential of your CVT with Dr. Pulley Sliding Roller Weights. Unlike traditional round rollers that can develop flat spots and stick in the variator ramps, Dr. Pulley’s patented non-round shape slides. This unique movement allows the variator to open wider for a higher top speed and retract further for better low-end acceleration, providing a broader range of gear ratios than any standard roller on the market.
These 19x17mm weights are a direct performance upgrade for the Piaggio Leader 150cc Engine found in:
Mechanic's Note: Orientation is everything with Dr. Pulley.
Installation Warning: Unlike round rollers, these MUST be installed in a specific direction; installing them "upside down" can damage your variator.
Tuning Tip: If you want more "zip" from a stoplight, go 1-2 grams lighter than your stock weights.
Pro Tip: While you're in there, check your Variator Slides—if they are loose or brittle, your new weights won't perform at 100%!
