Vespa V50 V90 V100 Primavera ET3 PK Gearbox Kit 58-54-50-46 teeth 3 to 4 Gear Conversion

Includes: 4 Gears, Gear Selector and Gear Cluster

If you need replacements for the gear cogs in your small frame motor we can save you the hassle of having to order each cog individually with our '4-gear PK' gear cog kit. The use of this gear kit it also the simplest method to convert your small frame motor from a 3 speed, to a 4 speed gear box. The extra gear cog enables a more effective exploitation of the power created by the motor. An advantage, even for the more mildly tuned motor setups!

The gear cog kit includes 4 separate output shaft gear cogs with 58, 54, 50 and 46 cog teeth respectively, an input shaft assembly with 4 gear cogs attached with 22, 18, 14 and 10 cog teeth respectively, a gear selector spider and a safety washer. If it is only the gear cogs that need replacing, you cannot go wrong with this gear cog kit and its unbeatable value-for-money. This kit fits the following models of small frame VESPA without any extra parts or indeed, modifications being necessary: VESPA 50S III/ Special V5B3TIII/ V5B4TII/ SR(D)/ 100 II/ 125 PV II/ ET3 II/ PK50/ S/ SS/ XL/ 2/ FL/ PK80-125S/ PK125/ ETS/ N/ XL/ XL2.

For the upgrade from a 3 speed gearbox to be made possible the following VESPA models also require an output shaft suitable for a 4 speed gear box to be ordered for successful inclusion in your motor setup: VESPA 50 I/ V5 A1T -> 92876/ 90 I/ V9 A1T -> 25000. 3 speed PK models do not require a replacement output shaft as the existing shaft can already handle the extra gear cog.
