zuma gears won't, the closest thing would be vino gears, but I have no idea if they will work or not but I need something.

There's a European Company MBK http://www.mbk-europe.com/mbk/ That markets a C3 scooter there.(The Booster X) Polini makes a gearset for the MBK Booster X and Yamaha Vox Scooters. (So, it'll also work on the C3 and Giggle!) Any Polini Dealer can get you a set for about $130 + shipping. I've got one on the way! :D Gabe :patriot:

The Polini gearset for my C3 came in today. The tooth count is 51x16 for a 3.19:1 (3.1875) ratio. I just replaced my bald 130/90-10 rear tire with a 120/90-10 tire in anticipation of the higher gearing. I'll let you know how it turns out. Gabe :patriot:

The Polini part number is 202.1406 Enviromoto, <www.enviromoto.com> in Indianapolis is a Polini Dealer. Allow up to 90 days for delivery. (Things happen much more slowly in Italy, Obviously!) About $130. Gabe :patriot:

I Had my Shop's really excellent mechanic install the Polini gears last tuesday. Money very well spent! The transmission has to be completely disassembled to change the gears out. On the way to the shop (43 miles) my gps was showing 40 mph straight and level with 43mph coming off of the bigger hills.(Ah! The honesty of a gps! The C3's speedo lies like politicians (either party) running for reelection! :D ) The return trip showed not much difference in takeoff, with 43mph straight and level. However, now it's running 49.5 mph off of the larger hills! Hmmm! With a bit more grunt, that speed is likely attainable.....We'll see! Gabe :patriot:
