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. 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.
