Malossi HTRolls (rollers) are made with CPT material to a specific formula and their weight is marked on one side.

 

HTRolls are a replacement for the original rollers, and are available in a selection of sizes, allowing you to regulate your scooter's transmission ratio which in turn regulates its speed and acceleration.

Operation

 

Due to the rotation, the weight of the rollers becomes a centrifugal force; the higher the rollers weight, the lower the gear change time, and vice-versa.

 

Variator calibration

 

To optimize engine's performance, select rollers that in operation, maintain the engine at the highest power regime.

 

By diminishing the rollers weight the engine s RPM increases; on the contrary, by increasing the rollers weight the RPM decreases.
