Whether you're looking for that last fancy bit for your Vespa or can't find a factory gear box at all, Malossi has the answer.  Seriously nice looking gear box with several improvements over the factory design. Toss this in your Ciao, Bravo, Si, etc etc.

Comes with a whole bag of shims, bearings, seals, hardware, etc. Also comes with instructions! Be sure to read those before you start assembling this.  

From Malossi themselves:

This is the challenge: is it possible to improve the gearbox where the Malossi gears turn, super performing and above all more beautiful?

Die-cast aluminum, machined and finished in our lines. It looks like a carter but it's not: it's an artwork. The art of ennobling every single part of one of our favorite vehicles, the Ciao (this gearbox is suitable for Piaggio mopeds such as Ciao, SI and cousins of the range). The art of increasing performance, shaping the material within the limits imposed by physics and by factory dimensions.

What's new.

We added ribs to strategic sections to increase stiffness. We increased the diameter of the wheel shaft bearing and of all the others, and added ribs to compensate the increased performance.
All within the original space: the gearbox uses pressed needle bearings for all gearbox shafts, NBR oil seals with spring sealing lip and auxiliary lip and a labyrinth to trap the oil and at the same time allow the gearbox to " breathe".

What we have optimized.

The gearbox simplifies the gear housing, improves brake shoe operation with dedicated machined surfaces to guide it more accurately. Two concentric positioning bushes closed by five screws (one more than the original), with hexagonal cylindrical head. The gearbox uses high quality steel pins, pressed into the crankcase, for the lever and brake shoe pins. To improve rigidity, we have eliminated the gasket: everything is sealed with silicone paste as in the most modern vehicles (the LOCTITE® SI 5926 art. 4319441B that you find in our catalogue is perfect).
The gearbox is supplied complete with bearings, oil seals, screws and shims: everything needed for A perfect assembly with Malossi gears (but if you want you can also assemble it with the original gears).

ATTENTION: : the gearbox does not allow the vehicle to operate in "bicycle" mode.
