Dial in your CVT with the Prima 18x14mm Roller Weight Tuning Kit. This master set includes 12 weight sets ranging from 6g to 17g — 36 rollers total — so you can test multiple configurations to find the perfect balance of acceleration and top speed for your riding style and engine setup. Mix sets for 0.5g increments (e.g., 3x10g + 3x11g = 10.5g effective). High-quality composite construction resists flat-spotting during tuning.

18x14mm is the standard roller size for many 125cc–170cc scooters.

Check compatibility by measuring your current variator roller weights first.  18mm is the roller diameter, and 14mm is the roller width.  Note that many variator rollers will experience slight wear over time, and the diameter will decrease.
