Dr. Pulley 21x17 Sliding Roller Weights: Vespa & Piaggio

Dr. Pulley 21x17mm sliding roller weights for Vespa and Piaggio 250cc–300cc scooters. Unlike standard round rollers, Dr. Pulley's patented sliding shape allows the variator to open more fully — delivering a broader gear ratio, higher top speed, and crisper off-the-line acceleration. Set of 6. SKU: 1200-1113.

Key Features

• Patented non-round geometry — eliminates flat spots and uneven wear common with circular weights
• Broader gear ratio — variator retracts and extends further than OEM, improving both takeoff and cruising
• Self-lubricating SL9 nylon composite — resists heat buildup and reduces internal variator wear
• Available in 9g to 13g to match your riding style and modifications
• ISO 9001 certified | Made in Taiwan
