The malossi variator is the front pulley that drives the scooter's rear wheel through the belt. Scooters are built at the factory to change 3 automatic gears. The variator is the main reason that happens. malossi variators are designed to improve a scooter's performance in a simple way, with no bodges, and to change 5 gears instead of 3. They add one gear at the start and 1 at the end, making the action smoother. It fits with no modification at all, replacing the factory one and giving the drive belt more acceleration. Replacing the variator alone brings noticeably satisfying results from the very first kilometres. The kit includes: Variator body Variator cover Variator pin – spacer Rollers – weights (8 pcs) Slides 4 (pcs) Clutch release spring Grease There is full cover on every part — every spare separately at reasonable prices — for maintaining the kit after normal wear or for changing to rollers of a different weight. 1 year warranty.
