Vespa gear and primary ratios???

[Avantone]

Hi,

I could do with some help on available gear ratios for all types of Vespa, and just importantly what's compatible with what.

I've found bits and pieces on the web and enough to get me started, but could do with something a little more comprehensive.

Can anyone advise, chip in, or point me in the right direction?

thanks

Hi Tony,

PM me your email and I'll send you the spreadsheet that I did for my smallframe gearbox.
Its got all the available smallframe gears and primarys listed.

After all I only created it after seeing your Lambretta gearbox visualiser

The SIP catalogue is a good shout thats where I got a lot of my smallframe gearing info from. If your going to add DRT stuff too you can get lots of data from there site as well
