Dr. Pulley Sliding Weights (20x15) - Honda PCX, Navi, GY6

Upgrade your CVT performance with Dr. Pulley Sliding Weights. Unlike traditional round roller weights, these patented sliding rollers allow your variator to open further for higher top speeds and faster mid-range acceleration.

The unique composite nylon material is designed for low friction and high-temperature resistance, significantly outlasting standard weights by preventing the "flat spots" that typically hinder performance over time.

Key Benefits

• Increased Top Speed: Unique shape allows the belt to ride higher in the variator.
• Anti-Flat Spot Technology: Sliding motion eliminates the uneven wear common in round rollers.
• Self-Lubricating Material: Long-wearing nylon composite reduces friction and heat.
• Precision Tuning: Available in multiple gram weights to customize your take-off and top-end power.

Technical Specifications

• Dimensions: 20mm (Diameter) x 15mm (Width)
• Quantity: 6 pieces per set
• Material: Heavy-duty, low-friction nylon composite
• Fitment: Fits most 125cc-170cc GY6 engines and Honda 110-150cc scooters.

Note:  For optimal results, ensure your variator ramps are clean and free of debris before installation.

Note: If your 125+cc engine code contains "QM" or "FM", these 20x15mm weights are compatible.
