Replacement weights YASUNI designed for the variator, ideal for scooter riders and DIY enthusiasts looking to refresh their transmission with ease. These rollers fit into the YASUNI variator drum and play a key role in the behaviour of the CVT transmission: their mass and diameter influence the engine speed and the smoothness of acceleration.
Practical for regular maintenance, these rollers allow for consistent roller performance and help avoid jolts caused by worn or flattened weights. When replacing, be sure to check the condition of the ramps, the slider, and the bearing guides of the variator to ensure a uniform installation. Compatible with YASUNI variators designed for this diameter, they are particularly suitable for urban-oriented setups where flexibility and smooth gear shifting are desired.
Workshop tip: change all 9 weights in one operation to maintain perfect balance of the drum and avoid premature vibrations.
