Malossi Roller Weights 19x15.5mm 7.5g - 6 pieces (Manufacturer part number: 66 9420.N0)
These Malossi roller weights are made from CPT with a specific formula to provide a technical replacement part for the original variator. Supplied in a set of 6, they allow you to adjust the behavior of your urban scooter's primary transmission by influencing the engagement point 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 a standard 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 restore consistent acceleration response and optimize variator performance. Professional installation is recommended if you are not equipped.
