Weights - MALOSSI 20x14.6 mm - 14.5 g

Wear on the rollers is characterized by flattening on one side; the rollers can then no longer glide properly in the variator’s raceway. This results in poor acceleration and often a lower top speed, as the variator can no longer extend fully due to the reduced diameter of the rollers.

To prevent premature wear, we recommend using a PTFE-based dry lubricant instead of grease. Unlike grease, this lubricant is not flung out after just a few revolutions but remains permanently adhered to the variator.

NOTE: Please make sure to check which weights are required for your variator before ordering. Used vehicles often come equipped with sport variators that use a different weight size than the original ones.
Therefore, when selecting your vehicle, you may encounter sizes that are not originally used in your vehicle.

Tuning Tips

Only if the engine—for example, due to a different exhaust system—doesn’t reach its full power until higher RPMs than stock should you choose lighter weights. Otherwise, it will “run out of steam,” meaning it will have less power despite higher RPMs and accelerate correspondingly worse, even if it sounds sportier.

Sets with different weight classes are ideal for fine-tuning. You can also mix weight sets of different weights, e.g., 3x5 grams and 3x7 grams. However, these must always be positioned alternately in the variator to avoid creating an imbalance. In our example, this would result in a calculated average of 6 grams. The only drawback is that the heavier weights wear out slightly faster.

The clutch springs should only be selected after the variator has been tuned. Otherwise, they are often chosen to be too stiff in an attempt to compensate for variator weights that are still too heavy.

There is only one set of weights that allows the scooter to achieve both its best performance and acceleration. The weights cannot be used to influence top speed, unless they are chosen to be so light that the engine lacks the power to overcome the counterpressure spring.

The counterpressure spring should always be as soft as possible but as hard as necessary. This prevents the V-belt from slipping and ensures the drive system isn’t subjected to excessive friction, which would lead to wear and a loss of power.
