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 drilled except in the contact section area between the wheel and the crosspiece so as not to create breakage points.

Toothed wheels with the same Z as the originals, same stop between the gears and toothed band moved to optimize the engagement with the primary axis. The position of the driving tooth with the crosspiece and the spaces between the gear changes are unchanged.

Can be mounted as a replacement for the Piaggio gear wheels on the original shaft.
