Dr. Pulley
Dr. Pulley 28x20mm Sliding Roller Weights - Set of 8
Description
Upgrade your CVT with Dr. Pulley 28x20mm sliding roller weights — the premier performance choice for the Honda Silver Wing 400 and 600. Unlike traditional round weights that roll, these patented sliders slide to shift gear ratios more effectively, delivering a broader power range and smoother power delivery.
By allowing the variator to open further and close more deeply, Dr. Pulley sliders improve low-end acceleration for stoplight pulls while raising top-end cruising speed with reduced engine RPM. Sold as a set of 8.
Performance Benefits:
- Enhanced acceleration: Quicker take-offs and improved re-acceleration when passing
- Increased top speed: Unique shape allows the belt to ride higher in the pulley
- Eliminates flat spots: Patented design prevents flat-spotting common in round rollers, extending transmission component life
- Self-lubricating material: Specialized SL-9 low-friction polymer for consistent performance in high-heat conditions (U.S. Patent 7,276,004)
Weight Selection Guide:
- 26g (Performance): Significant boost in take-off and passing power without meaningfully hurting fuel economy — most popular upgrade for Silver Wing owners
- 28g (Fuel Economy): Stock weight equivalent — retains smooth shifting and longer component life vs. round rollers
- 19g Black Pearl (Racing / High Altitude): Recommended for aggressive performance applications
Note: Product color may vary (cream or Black Pearl) depending on gram weight selected.
