Buddy 125 takes 11.5g stock rollers, and Blur takes 14g stock, so play with some different weights and make it rip!
For those of you unfamiliar with roller weights, they are an important tuning device and have a significant impact on your scooter's performance! They should be checked/changed every 1000 miles (per maintenance schedule) to keep your scooter running tops. Over time, roller weights will develop flat spots which will impair the performance of your scooter.
A good indication that your rollers are worn is increasingly high revs for a given speed and/or decreased top speed. Replacing worn rollers with will restore and actually improve your low-end power and especially your top speed. Fuel efficiency will also improve dramatically!
Includes 36 Roller Weights, from 6g to 17g. Lighter roller weights will increase RPM for any given road speed. Heavier weights will lower RPM for any given road speed. Must be put in a 120° pattern!
