Polini
Polini 16x13 Roller Weight Tuning Kit - 36 piece set
Description
Optimize your scooter's performance with the Polini 16x13 Roller Weight Tuning Kit, which lets you test different weight options before choosing a permanent set. Try lighter weights for a higher-revving launch and hill pull, or heavier ones for a lower-revving cruising feel; the result depends on your complete variator setup.
Key Features
- Four Weight Options in One Kit: Includes 4.5g, 5g, 5.5g, and 6g rollers — covering the full tuning range for most 50cc CVT setups.
- Complete Set Per Weight: Each weight size includes 6 brass center weights that pair with the outer roller, giving you a full replacement set to test each configuration properly.
- 16 x 13 mm Roller Dimensions: Precision-matched to factory variator roller pockets on compatible 50cc engines.
- Polini Quality: Manufactured by Polini, a trusted Italian performance brand with decades of two-wheel motorsport engineering.
