Dr. Pulley 20x15 Sliding Roller Weights: Honda PCX, Navi

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 take-off and top-end power.

Technical Specifications

• Dimensions: 20mm (diameter) × 15mm (width)
• Quantity: 6 pieces per set
• Material: High-resistance SL-composite nylon
• Fitment: Fits Honda 110–150cc scooters and GY6 "B-Case" engines or performance builds with modified variators... always measure to confirm!

Fitment note:

• Standard GY6 (125cc/150cc): The vast majority of Standard GY6 engines (found in brands like TaoTao and Ice Bear) use 18x14mm rollers. If you try to put 20x15mm weights in a standard variator, they physically won't fit or will bind immediately.

• GY6-B / ZNEN Variants: Some high-end Chinese scooters (often manufactured by ZNEN) use a "B-Case" engine or a modified variator that do accept these larger 20x15mm weights.  Measure to confirm!

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

Note: Performance upgrades are considered racing parts and are not covered by warranty.
