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
