{"product_id":"dr-pulley-20x17-sliding-roller-weights-vespa-piaggio-200","title":"Dr. Pulley 20x17 Sliding Roller Weights - Vespa\/Piaggio 200+","description":"Dr. Pulley 20x17 Sliding Roller Weights unlock the true potential of your Vespa or Piaggio 200–300cc CVT. Unlike traditional round rollers that develop flat spots and notches over time, Dr. Pulley’s patented non-round shape slides through the variator ramps — allowing the variator to open wider for higher top speed and retract further for stronger low-end pull. Available in 9.5g–13g to match your riding style. SKU: SR2017. Installation Note: Orientation is critical. The “blocked” side of the slider must face the direction of rotation. Inspect variator slides for wear before installing — worn guides will prevent smooth sliding action. Key Features Patented sliding geometry — prevents flat spots and uneven wear common with round weights Extended gear range — sits lower in ramp for explosive take-offs, pushes higher for top speed Self-lubricating high-temp nylon composite — outlasts standard OEM rollers Available in 9.5g, 10g, 10.5g, 11g, 11.5g, 12g, 12.5g, 13g — select from dropdown Fits OEM and most aftermarket variators Weight Selection Guide Lighter (9.5g – 10.5g): Better hill climbing and city acceleration; higher RPM cruising Mid-range (11g – 12g): Balanced daily commuting performance Heavier (12.5g – 13g): Higher top speed and lower RPM cruising on flat roads Specifications Size: 20mm x 17mm Weight Options: 9.5g – 13g (6 per set) Quantity: 6 sliders per set Material: Self-lubricating low-friction nylon composite Made in Taiwan SKU: SR2017 Compatibility Brand \/ Model Engine Vespa Granturismo 200 200cc Leader Vespa GTS \/ GTV 250 \u0026amp; 300 250cc Quasar \/ 300cc HPE Piaggio BV 200 \/ 250 \/ 300 Leader \/ Quasar \/ HPE Aprilia Scarabeo \/ SportCity 200–300cc Piaggio-based Visit our Shop by Diagrams page to confirm fitment for your specific model year.
