When you change Tire size on a 250ex is it like changing sprockets

hey guys i realise a smaller tire = more accel les top speed, but you know how if you drop a front sproket size you wrap out quicker your roost dust farther in a straight line does it work like that with changing your rear tires? also does front tire size do anything?

yup the smaller the tire the more accelaration and less top speed

I replace the stock ballons w/ some 20" used tires and it handles better and it's a lot quicker, but yeah top end suffered a little. An aftermarket CDI would take care of that.
