Malossi HT-Rolls Variator Weights 16x13 mm – 3.3 g for clean variator performance

With the Malossi HT-Rolls variator rollers (16x13 mm, 3.3 g), you get precision-engineered variator weights from the well-known Italian tuning forge Malossi. The rollers are made from a highly wear-resistant material and impress with extreme accuracy in dimension and weight – exactly what you need for a finely tunable variator.

The slightly higher purchase price pays off quickly: thanks to the long service life and better sliding behavior, the variator runs noticeably smoother. Particularly practical: the Malossi weights are used without grease because the surface is self-lubricating. Ideal if you want to optimize your tuning on a Yamaha Aerox 50, Piaggio NRG 50, or Vespa Primavera 50 – and of course for many other compatible models.
