20×12 Round Roller Weights for the Linhai 260/300, Yamaha Morphous 250, Yamaha Vino 125, Yamaha Zuma 125 and many more.
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 this set will restore and actually improve your low-end power and especially your top speed. Fuel efficiency will also improve dramatically!
So what weight is right for you? We are here to help. The lighter the weight the faster the take off, the heavier the weight the better the top end speed. Rollers are the way you set the engine speed. Lighter weight raise engine speed, heavier weights lower engine speed. Be careful, higher is not always better as you can rev right past your torque curve and just spin out without any thrust. Too heavy a weight and you will be below your torque curve. Using rollers to experiment with the proper weight can be very rewarding. So what are you waiting for get rolling grab some today!
