Malossi Roller Set 23.8x18mm 18g - 6 Pieces (Ref. 66 9915.A0)
These Malossi rollers, made from CPT with a specific formula, are designed for the variator of scooters. They provide a high-quality technical replacement for the original rollers and allow you to adjust the variator's pivot point to influence the engine's RPM and acceleration.
Principle
When rotating, the weight of the rollers generates a centrifugal force that pushes the rollers outward from the variator. By selecting an appropriate roller weight, you change the RPM at which the variator engages, thus affecting the engine's operating range.
Choosing the right roller weight is part of the essential adjustments to optimize the variator's response: lighter rollers tend to favor higher RPMs, while heavier rollers delay engagement and stabilize the torque range. These Malossi rollers integrate into precise tuning to adapt the transmission to the rider's preferences.
