GEARBOX GEARS Malossi Z 55 / 40 / 37 / 36 FOR VESPA PX GEARBOX - What

Wheels made with special cementation steel, the wheels are obtained with CNC gear cutting machines and the wheels are ground in the contact surfaces. In the contact surfaces between the gears we have obtained small pockets useful for transporting the oil to increase and ensure lubrication between the walls that slide between them. The number of teeth has been calculated to give an optimized transmission ratio. In all the wheels where it was possible to do so, lightening holes have been made except in the contact section area between the wheel and the crosspiece so as not to create breakage points.

Kit with Z different from the original useful for providing a variable transmission ratio based on needs.

The wheels can also be purchased individually to customize the transmission ratios in the 4 gears:
