Description

Upgrade your scooter's transmission performance with premium Dr. Pulley 18x14mm Sliding Roller Weights. Unlike traditional round roller weights that can develop flat spots over time, Dr. Pulley's patented composite sliding geometry features a multi-faceted profile that slides smoothly within the variator ramps. This unique design allows the variator to open wider and close further—delivering faster low-end acceleration, smoother mid-range transitions, and a notable boost in top-end cruising

  • Patented Sliding Geometry: Eliminates the traditional "flat spotting" common to round weights, drastically extending part service life.
  • Optimized Variator Travel: Allows the drive belt to drop lower into the boss at startup (better takeoff) and climb higher at peak RPM (increased top speed).
  • Self-Lubricating Composite: Formulated from a high-density, low-friction nylon material that resists heat saturation and minimizes variator ramp wear.
  • Tuning Flexibility: Perfect for restoring factory performance or fine-tuning transmission engagement characteristics.

CRITICAL INSTALLATION NOTE: Directional orientation is vital for sliding weights to function correctly. Sliders must be installed in a specific direction within the variator stalls. Please refer to the included factory instruction diagram to ensure the designated "curved" face is oriented correctly against the variator ramp wall before buttoning up the transmission case.

Tuning Mechanic's Advice: Choosing a weight gram profile that is lighter than stock will deliver crisper acceleration and better uphill pull. Selecting a weight profile identical to factory spec yields enhanced top-end speed without a loss of acceleration.  Selecting a weight profile heavier than stock will deliver the maximum top-end speed with a corresponding drop in acceleration.
