MALOSSI Roller Set 19x17mm 8.7g - 6 pieces (Manufacturer Ref: 66 9456.F0)
Designed by MALOSSI for urban scooter transmission, these rollers made of CPT (specific formula) are offered as original technical replacements. The kit includes 6 rollers measuring 19 x 17 mm, each weighing 8.7 g, allowing for adjustment of the variator's behavior and refining the engine's response during daily use.
Features
- Diameter: Ø 19 mm
- Width: 17 mm
- Number of rollers: 6
- Unit weight: 8.7 g
- Material: CPT (specific Malossi formula)
When rotating, the mass of the rollers generates a centrifugal force that affects the opening of the variator: lighter rollers delay the engine's rev-up, while heavier rollers accelerate it. This set allows for the adjustment of cruising RPM to keep the engine within its desired power range based on your riding style (urban trips, frequent accelerations, stop & go).
Compatible with many 125 cc urban scooters — for example, PIAGGIO MEDLEY 125 IE S ABS (2024), APRILIA SR 125 MOTARD (2016), and DERBI VARIANT 125 SPORT (2014) — this kit is aimed at riders seeking precise variator tuning without altering the original architecture. Professional installation is recommended for optimal adjustment.
