Genuine Stella Automatic 18x12mm Roller Weights

Variator Roller Weights for Genuine Stella Automatic

These 18x12 mm variator roller weights are made to adjust or alter the CVT behaviour of your Genuine Stella Automatic. A pack contains six rollers, offered in 8 g, 9 g, and 10 g weights. With these choices, you can tune the variator to match how you ride. They are among the Genuine Stella scooter parts you can pick up to help refine your scooter's response.

Tuning Your CVT Response

These rollers play a key role in how the transmission behaves. Lighter rollers generally let engine RPM climb higher before the unit shifts up, whereas heavier rollers bring the upshift in sooner. Swapping out worn rollers with this set can help bring back proper CVT operation.

Compatibility and Use

These roller weights suit the Genuine Stella Automatic 125 and other CVT systems that use 18 × 12 mm rollers. Check the roller dimensions before ordering. For the most even results, replace the full set in one go so the weights stay balanced.
