With the Malossi MHR overrange variator you will be giving it the best chance to obtain the full potential of the engine. Pitch angle and trajectory of the roller weights offer a great increase in performance in contrast to ordinary sport variators. This is reflected in more top speed and wider range. The Malossi MHR overrange kit is becoming one of the top candidates for high end tuning.

Piaggio engines manufactured from AD 98 have a larger pulley, so this kit does not include rear pulleys. The original pulleys work perfectly with this kit.
This new system based on the new Fixed pulley torque correction pulley with a larger diameter and absolutely cutting-edge technological features. The larger diameter of this pulley makes it possible to have a considerably higher transmission ratio stroke compared to the original pulley, which has a considerably smaller external diameter.

The Malossi technicians have taken care of even the smallest details in the realization of this pulley using special material and a particular type of thermochemical treatment that confers a very high resistance to erosion and a high mechanical resistance. This new fixed pulley has been made to have a perfect operationif it is coupled to the Malossi torque corrector (Torque Driver), having the same diameter as the fixed pulley. All this with the experience of competition


In order to enjoy the regime of the new torque correction group and the power now available in the competition vehicle, a new Kevlar® Malossi timing belt (K belt) with oversized section has been introduced and updated length to ensure maximum performance in all operating conditions.
