CVT Variator Malossi MHR Multivar Booster X / Yamaha Giggle 50cc 4-stroke

Malossi MHR

The MHR series from Malossi is generally available in 3 categories for the most popular models:

• MHR Replica
• MHR Racing
• MHR Team

The 3 model series differ in terms of performance and competitiveness. The MHR Team series includes the top-of-the-line  models with outstanding performance for racing. The MHR Racing is in the middle, and the MHR Replica adopts the basic features of the higher versions, with the emphasis on reliability for everyday use rather than maximum performance for the race track.

Malossi Multivar

The Malossi Multivar range includes all Malossi tuning CVTs, whether for scooters, mopeds or maxi scooters.

The Multivar CVT range includes the Multivar 2000 and the Multivar MHR. Both transmissions increase engine performance, with a focus on improved acceleration and responsivity. The Multivar 2000 variator is suitable for less powerful engines, the Multivar MHR for more heavily tuned engines.

For very powerful engines or engines with a considerably increased displacement, consider getting an overrange CVT.

scooter CVT

Modern scooters are equipped with a continuously variable transmission, the so-called CVT, also called variator.

CVT Parts:

• Front pulley, movable. It contains the variator weights and has a special shape with an inclined surface to allow the V-belt to move freely up and down.
• Ramp plate: Holds the weights in place.
• Variator sleeve: Serves as a bearing for the variator, which moves axially back and forth, i.e., opens and closes.
• CVT roller weights: Adjustment weights that play a critical role in function and performance.

original, Sport and Oversize CVTs

• Original: Original or OEM quality CVTs are equipped with a restrictor to limit the speed to 45km/h. There are riders who remove the restrictor to derestrict their scooter and unleash the full performance without restrictions.
• Sport: Sport CVTs are lighter than the original and are characterized by special angles and a special coating, which increases the top speed, but especially acceleration.
• Oversize: Based on the same principle as the Sport CVT, but has larger dimensions. With an oversize / overrange vario, the performance of the scooter can be increased even further.

You should also always replace the V-belt when replacing the CVT or go for a complete CVT kit.
