Prima CVT Roller Weight Set 18x14mm – Buddy 125/150/170i GY6

Description

Fine-tune your CVT performance with Prima 18x14mm CVT Roller Weights. Sold as a set of 6 black composite barrel rollers with gold brass center bushings. Changing roller weight shifts the CVT shift curve — lighter rollers favor low-end acceleration and hill climbing; heavier rollers raise top-end speed on open roads. Select your weight above.

Weight selection guide: Genuine Buddy 125 uses 11.5g stock; Blur uses 14g stock. Lighter than stock improves off-the-line response. Heavier than stock raises top speed. Heavier riders or stock engines benefit from lighter rollers; lighter riders or big bore builds can run heavier.
