Features:

• The rollers should be checked/changed every 1600km/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. One will have this sooner as others and this based on the performance from your engine, your personal drive style and your variator type.
• If you spend a lot of time on top speed then this will demand a lot more from both, your roller weights and your v-belt, so both will need to be replaced sooner in this case as if it would be the case for someone with a moderate drive style.
• 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.
