GEARWHEEL SET FOR VESPA Z.55/40/37/36 GEARBOX

Wheels made with special case-hardened steel, obtained with CNC hobbing machines and 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 guarantee lubrication between the walls that slide between them. The numbers of teeth have been calculated to give an optimized gear ratio. In all the wheels, where it was possible to make them, lightening holes were made except in the area of the contact section between the wheel and the gear selector so as not to create breaking points.

Kit with Z different from the original useful to give a variable transmission ratio according to the needs.

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