Description

Upgrade your CVT performance with Dr. Pulley 20x15mm Sliding Roller Weights. Unlike traditional round rollers that develop flat spots over time, Dr. Pulley's patented sliding geometry allows your variator to open further — delivering higher top speeds, faster mid-range acceleration, and longer service life. Made from a self-lubricating high-temp nylon composite. Sold as a set of 6.

  • Patented sliding shape prevents flat spots common in round rollers
  • Allows variator to open further for higher top speed and better belt range
  • Self-lubricating high-temp nylon composite for extreme longevity
  • Available in multiple gram weights for custom CVT tuning
  • Set of 6 matched weights

Specifications

  • Dimensions: 20mm (diameter) x 15mm (width)
  • Quantity: 6 per set
  • Material: High-resistance SL-composite nylon
  • Weight range: 10g–18g (select from menu)
  • SKU: 1200-1201

Weight Selection Guide

  • Lighter (10g–12g) — faster acceleration, better hill climbing, high-RPM riding
  • Mid-range (13g–15g) — balanced daily commuting, similar to stock but smoother
  • Heavier (16g–18g) — maximum top-end speed, lower cruising RPM

Compatibility

Brand / Engine Compatible Models

Fitment note: Standard GY6 125/150cc engines (TaoTao, Ice Bear, etc.) use 18x14mm rollers — 20x15mm weights will not fit. Some high-end Chinese scooters with GY6-B or modified variators do accept 20x15mm. Measure your variator to confirm before ordering.
