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 of 6 rollers measuring 19 x 17 mm, each weighing 8.7 g, allows for adjustment of the variator behaviour and fine-tuning of the engine speed and responsiveness for daily use.
Specifications
When rotating, the mass of the rollers generates a centrifugal force that affects the opening of the variator: lighter rollers delay the engine speed increase while heavier rollers hasten it. This set thus allows for adjustment of the cruising speed to keep the engine within its desired power range according to your riding style (urban trips, frequent accelerations, stop & go).
Compatible with many urban 125 cc 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.
