Malossi Roller 17 x 12.3mm for TGB 50cc / Aprilia SR50 Ditech
TGB run a roller weight of 8.9 Gram in original variator.
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.
With a variator your scooter has that extra sprint, a consistency in shifting, a greater mechanical ease at high speeds and a constancy in performance you’ve never experienced before with the original variator.
This is what the Malossi technicians wanted to obtain.
