Prima 19x17mm CVT Roller Weight Set of 6 | Vespa 150
Description
Fine-tune your scooter's CVT performance with Prima 19x17mm roller weights. Swapping roller weight changes how your variator ramps up through the gear ratio — lighter rollers favor acceleration and hill climbing, heavier rollers favor higher top speed on open roads. Sold as a set of 6.
Tuning Guide
- Lighter rollers (10g): Better acceleration, stop-and-go riding, and hill climbing — lower top speed
- Heavier rollers (11g): Higher top speed on long roads — slower low-end acceleration
- Heavier rider / stock motor: Lean toward lighter rollers
- Lighter rider (under 140 lbs) / big bore kit: Lean toward heavier rollers
