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.
