MALOSSI Roller Weights 19x15.5mm 7.5g - 6 pieces (Manufacturer's ref: 66 9420.N0)
These Malossi rollers are made from CPT with a specific formula to provide a technical replacement part for the original variator. Supplied in packs of 6, they allow you to adjust the behaviour of your urban scooter's primary transmission by influencing the engagement moment of gear shifting and acceleration.
Principle
The rollers convert their mass into centrifugal force during the rotation of the variator: lighter rollers promote a higher engine speed before shifting up, while heavier rollers lower this speed. Adjusting the weight (here 7.5 g) helps you keep the engine within its power range according to your usage.
Compatibility / usage: ideal for urban scooters equipped with an original-type variator. Examples of common compatible models: PIAGGIO TYPHOON 50 E4 (2020), DERBI VARIANT 50 SPORT R (2016), GILERA RUNNER 50 BLACK SOUL (2015).
Replace worn rollers to regain consistent acceleration response and optimise the behaviour of the variator. Installation is recommended by a professional if you are not equipped.
