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.
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.
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.
