    this is my new project where I want to realize a 3-Gear Bravo.

    For that bought a 2-Gear Bravo in very bad condition but with papers and for little money.

    today I started with disassembly to give it a new painting

    there are not much parts left for painting, nice thing such a Bravo. 😀

    tomorrow I will grind the frame, and maybe also painting

    Never knew there were 3 speed parts available for Piaggio Vespa. I did know there were 2 speeds. Great work you’ve put in so far. The Bravo is a great base to work on. I will follow the progress:thumb

    Looks good!

    My 3-speed gearbox got different gears in it. :!, The gears on the main axle in my 3-speed are smaller.

    So it looks like there are different 3-speeds just like the 25 and 45kn/h 2-speeds.

    Has yours got a neutral?

    yes, it has neutral between 1st and 2nd gear.

    What ratio does your 3-speed gearbox have in the 3 gears?

    Mine is about:
    >1st- 14,5:1
    >2nd- 10:1
    >3rd- 7,5:1

    Mine does not have a neutral. I don’t remember the amount of tooth on the gears but the ratio’s are:

    1st 12.5:1
    2nd 9.5:1
    3rd 6.5:1

    this Italien Moped builders. 😀

    They are building a hand full of 3-speed gearboxes, and this in addition with ratio variants.

    So it looks that yours is a little longer then the one I’ve build.
    How is it drivable with a standard engine, or are you runing it with a tuned engine?

    I haven’t driven with this gearbox yet. The treads in the topplate are completely gone. I just boughtt a second hand plate from Billy and still need to mount it.

    Last month i made a new subframe for the vespa Si so that the 2/3 speed fits in there.
