HTRoll Calibrated Rollers With High Precision for original speed variators and Multivar. HTRolls are made with CPT with a specific formula and their weight is marked on one side. HTRolls represent a technical spare part for the original one, 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, the weight of the rollers becomes a centrifugal force the higher the rollers weight, the lower the gear change time, and vice-versa.

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