My new bike has good take off but doesn't have a very good top speed because it is only a 4 speed. So me and Dad were thinking of changing the sprockets. At the moment it has a 15 tooth on the front and a 40 on the back. So we are thinking of putting a bigger one on the front. How much bigger would you go. Or would it be better to change the back sprocket. Confused Confused Confused Smile

if you are going to change the sprockets its probly easier to change the front around just go 1 or 2 teeth bigger!

ahhh yes but goin up 1 on the front is like going down 3 on the back... so it may be too coarse an adjustment...

i would drop 1 or 2 teeth on the back and see how that goes.

bigger tyres will do same thing as changing your gearing too

U think I am going to have to go down a few on the back because I had another look yesterday at it and I dont think a bigger front will fit on. It will hit the motor. My dad said about bigger tyres but sprockets will be a bit easier and cheaper at the moment caus I still don't have much money and tyres cost a fair bit. Might get them later though and find the best combo of sprockets and tyres. Rolls eyes Anyway now all I have to do is find one that will fit my bike. Very Happy
