Vespa PX E Arcobaleno Electric Starter 150 [1981-1997] - Gear set Z 55/40/37/36 for Vespa

Gear set Z 55/40/37/36 for Vespa PX E

The MALOSSI gear set is designed for the Vespa PX E Arcobaleno Electric Starter 150 in the 1981-1997 model year range. The coordinated gear combination supports the adjustment of the gear ratios in the four gears and thus provides a targeted basis for tuning the transmission.

Function and execution

• Gear combination with 55, 40, 37 and 36 teeth
• Gear ratio for the four gears is specifically calculated
• Made from specially hardened steel
• Manufacture with CNC hobbing machines
• Ground contact surfaces for gear mesh
• Small depressions on the contact surfaces support oil transport and lubrication of the sliding surfaces
• Relief holes, if structurally possible; recessed in the contact area between the gear and gear selector lever

Translation adjustment

The set uses a different number of teeth than the original version. This allows the gear ratio to be varied according to the respective coordination needs. The gears are also available individually and can be selected separately to adjust the gear ratios in the four gears.
