Ultimate CVT Performance: Dr. Pulley 18x14mm Sliding Weights

Standard roller weights operate by rolling up and down the variator ramps, which eventually leads to "flat-spotting" and inconsistent shifting. Dr. Pulley Sliding Weights revolutionize your transmission by sliding rather than rolling. This patented wedge-shaped design allows the weights to travel further in the ramps, effectively broadening your gear ratio for better low-end takeoff and increased top-end speeds.

Performance Advantages

• Broadened Gear Ratio: Allows the variator to open further for higher top speeds and close tighter for better low-end torque.
• Eliminate Flat Spots: The sliding movement prevents the uneven wear common in round rollers, significantly extending the service life of your transmission components.
• Enhanced Throttle Response: Improves re-acceleration properties, making your scooter feel more responsive when overtaking or climbing hills.
• Self-Lubricating Polymer: Made from a high-tech, low-friction material that resists heat and reduces wear on the variator ramps.

Installation Note: Orientation is critical! Sliding weights must be installed in a specific direction to function correctly. Refer to the included diagram to ensure the "curved" side is facing the proper direction within the variator. Tech Tip: If your engine code includes "QM" or "FM", this product is compatible with your vehicle. For the best result, we recommend choosing a weight 10-15% lighter than your stock round rollers for a balance of acceleration and top speed.
