It is a fixed semi-pulley with a diamond-shaped finished belt sliding surface, and with a recalculated angle to widen the gear change range. This replacement complements Malossi''''s Multivar to make it unstoppable. Designed for the line of scooter variators, it further improves the operating conditions of the transmission belt. It is not just an accessory, but a very important part of the durability of all transmission components. The temperatures generated inside the crankcase, which is where V-belt variators operate at critical moments, are prohibitive and sometimes certain components, such as drive belts or variator rollers, are irreparably damaged. There are cases where the rollers can reach the melting point. In addition to other advantages, the Ventilvar has a greater cooling capacity than the original semi-pulley, which makes it essential for safe and sporty driving.
Note: it can be combined with the Multivar and with the original variator. Products reserved exclusively for competitions in designated places according to the provisions of the competent sports authorities.
