Malossi Secondary Gear Set Zip / LX / ET4 - 10" Crankcase - 6712144

With this secondary transmission kit, you can change the scooter's standard gear ratio, resulting in (even) more speed. This only works well if you've also taken other measures to increase the engine's horsepower.

Otherwise, acceleration would be difficult. But combined with a different cylinder, variator, and ECU, it runs like a charm. You'll be amazed at what your scooter is capable of.

NOTE: THIS SET ONLY FITS SCOOTERS WITH A 10 INCH CRANKCASE
