Prima Roller Weight Tuning Kit (16x13) — 3g to 14g (36 Total Weights)
Stop guessing and start tuning. The Prima Roller Weight Tuning Kit is the ultimate diagnostic tool for anyone looking to dial in their scooter's CVT performance. Whether you are aiming for explosive low-end wheelie power or trying to find that extra 5 MPH of top-end speed, this kit provides the full spectrum of weights needed to find your engine's "sweet spot." Instead of buying multiple individual sets, this all-in-one master kit allows you to test, swap, and perfect your transmission's behavior in a single afternoon.
