Dr. Pulley 19x17 Sliding Roller Weights - Vespa 150cc

Dr. Pulley 19x17 Sliders 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. Technical Performance Features Patented Sliding Shape: Specifically designed to prevent the uneven wear and "wedging" common with round weights, ensuring consistent performance over thousands of miles. Broadened Gear Ratios: The specialized geometry allows the weight to sit lower in the ramp for explosive take-offs and push higher at the top end for increased cruising speeds. Self-Lubricating Material: Composed of a high-density, low-friction nylon material that reduces heat buildup and extends the life of your variator and drive belt. Precision Tuning: Available in various gram weights to help you customize your scooter's power delivery to match your specific riding style or exhaust setup.

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%! SKU: SR1917 Vendor: Dr. Pulley
