Roller weights -RMS- 21x17mm 13.8g x6

Standard rollers for RMS variator with size 21x17mm.The weight of the variator plays a major role in tuning scooters.Base rule: The lighter your rollers, the more revolutions are needed to push the rollers to the end by centrifugal force.Heavier rollers need from less speed to start this process.This means that if your scooter has lighter rollers, it needs higher revs to start. With heavier rollers you will start at lower speeds.Each driver must find out which speed is suitable for him, this is done with samples of different weights.Our advice!By changing the variator rollers, each scooter can be adjusted exactly to its driving conditions. You should keep in mind that the more tuned the scooter, the more sensitive it is to changes in the weight of the variator rollers. Be careful not to experiment with too different weights on the rollers. Remember: The exact Due to the rotation, the weight of the rollers changes to centrifugal force, the heavier the rollers the earlier the speed changes and vice versaа it is really necessary so that you do not lose engine power. Too light rollers force the engine unnecessarily, and with too heavy rollers you will not get any acceleration.
