gear ratio

im looking to upgrade my 2011 tomos lx. im getting biturbo and carb speed kit from 1977 mopeds. they are out of stock on the 22t rear so i was think 20t for the rear. what should the front be?

27x22 seems to be the best set up. You can find them on ebay too.

Re: gear ratio

Careful what you choose, you usually have to do some modifications to get them to fit. I think 27x22 is the best setup

Re: gear ratio

If you go with a 20 rear, be prepared to grind your wheel for it to work. Wait for the 22 to come in stock and get a 27 front. You could try treatland...

Re: gear ratio

yep you have to grind the wheel for a 20. its no biggy if you have a grinder and some time. totally worth it! or do what we did and put a 16t on the rear! c;

Re: gear ratio

You have an a55, make sure you get the right rear sprocket.
