These calibrated, high precision rollers by Malossi work with the original speed variator and Multivar. The Malossi Rollers are made with a specific formula of CPT. Each roller is marked on the side with their weight. The Malossi rollers are a more technical, and precise part over the original ones, in a complete series of calibrated elements capable of varying your scooter's transmission ratio and perfectly regulating its speed and acceleration.

Operation
Due to the rotation of the variator, the weight of the rollers creates centrifugal force; the higher the rollers weight, the lower the gear change time, and vice-versa. To optimize your engine's performance, select rollers that, in operation, maintain the engine at the highest power regime. By decreasing the rollers weight the engine s RPM increase; on the other hand, by increasing the rollers weight the RPM decreases.
