WOTTAN teams up with MALOSSI to launch the WOMO variator, a unique integrated solution to improve the STORM-S riding experience for now.

The objective of this alliance has been to develop an exclusive, custom-made variator that improves power delivery throughout its rpm range, transmitting better acceleration response and providing the rider with an experience of greater control and safety.


MALOSSI has developed a variator for the STORM-S exclusively for WOMO. With this variator the rider is the true master of the steering, the throttle controls are transferred directly to the wheel, giving the best performance for the engine.


The product has been developed to guarantee maximum durability and minimum maintenance.


The graph shows two curves: one in black represents the scooter with the original variator, while the curve in red represents the scooter with the Malossi WOMO variator.

In the curve above, you can see the RPM graph, which shows a higher performance with the WOMO variator compared to the original variator. When accelerating, the scooter reaches almost 8.000 RPM, which is the maximum power output of the engine, in contrast to the 7.500 RPM offered by the original variator.

In the curve below, the acceleration graph is shown, and it is clear that the Malossi WOMO speed variator achieves the same speed as the original variator, but in a shorter time.


With the WOMO variator, the engine becomes more comfortable, smoother and quieter than with the conventional variator.

With the WOMO variator, the pulley reacts immediately when the throttle is opened or closed.

Increases the rider’s feel for the scooter: allowing for better throttle feel and quicker response.

Powerful output under control.

When the inverter is fully open, the maximum speed increases.

Power delivery: always keeps the engine at maximum power throughout the rpm range.

Instant power delivery

Maximum engine performance optimisation.
