Malossi HT-Rolls Variator Weights 19x15.5 mm – 9.3 g for precise CVT tuning

With the Malossi HT-Rolls variator rollers, you bring proven Malossi quality directly into your variator. The Italian tuning specialist Malossi has always stood for power, precision, and reliable performance. These rollers are manufactured from a highly wear-resistant material and impress with extreme accuracy in dimension and weight – exactly what you need for a cleanly operating variator.

The slightly higher purchase price is worth it: due to the longevity and the better sliding behavior, you will quickly recover the cost in everyday use. Important: The Malossi weights are used without grease, as the surface is self-lubricating.

Fits many rollers and scooters – for example, models from Piaggio, Vespa, and Aprilia, but also numerous other vehicles from the list below. This setup is particularly popular among Piaggio and Vespa riders seeking a precise tuning of the variator.
