Ok I went up to a 13 T on the lt80 with the 22 rear. But I was thinking maybe going to 14/26. Would I get the same speeds and low end?

Also I've always heard 4T on the rear = 1T on the front. Is this right? How many teeth equals 1" on tire size?

And if you do go bigger on the front you can't pull the R's out of the motor as good. So if you go bigger in the rear does this really help?

 

Voodoo I read an article in Dirt Wheels that said that 1 tooth differance on the front is equal to 6.6 teeth on the rear. We raced flat track before going to MX and the 6.6 to 1 ratio is very close. Some say that if you go to small on the front it will cause more resistance as the chain rolls around the smaller sprocket. Some say that a larger front sprocket has more rotational mass on the front and slows acceleration. I'm not sure how you would messure the resistance either way. It probably isn't noticable to the average machine. I always felt that a smaller sprocket on the front let the bike rev quicker but that is only my opinion and observation from my experience. Having an assortment of different size rear sprockets let you better dial in gearing on different tracks. I don't know the mathmatical formula but I hope this helps a little.
