Malossi HT-Rolls Variator Rollers 19x15.5 mm (3.0 g) – precise variomatic weights for clean tuning

With the Malossi HT-Rolls, you bring a piece of Italian tuning expertise to your variomatic. Malossi has always been known as a tuning forge and traditional company – and that is exactly what you notice with these variomatic weights: extreme precision in dimension and weight, combined with a highly wear-resistant material.

Especially for setups on popular scooters such as Vespa Primavera 50, Piaggio Zip or Yamaha Aerox 50, well-tuned rollers make the difference: the response becomes cleaner, the variomatic works more defined and you benefit from smoother gliding behavior. The slightly higher price pays off quickly – through longevity and the high-quality surface.

Important: The Malossi weights are installed without grease, as the surface is self-lubricating.
