17x12mm Scooter Roller Weight Set 6-Pack | Universal Parts
Description
Fine-tune your CVT transmission with this Universal Parts 17x12mm roller weight set. Available in 0.5g increments from 4.0g to 8.0g — select your weight at checkout. Six matched rollers per set, calibrated to strict tolerances for smooth, vibration-free CVT operation. Wear-resistant polymer construction resists flat-spotting under high heat.
Tuning guide:
- Lighter (4.0g–5.5g): quicker off-the-line acceleration and better hill climbing — best for heavier riders or stock motor setups
- Heavier (6.0g–8.0g): lower cruising RPM and higher top-end speed — best for lighter riders or big-bore builds
- Always install rollers dry — never grease a dry-roll CVT variator
