What sprocket size should I get?
This is determined by the the number of teeth on the front sprocket, compared to the number of teeth in the rear sprocket. For example, a motorcycle with a 17-tooth front sprocket and a 45-tooth rear sprocket would have a ratio of 2.65 (45 divided by 17 = 2.65).
Is more teeth on a rear sprocket better?
Adding teeth to the front and rear sprockets have opposite effects. Installing a larger countershaft sprocket creates higher gearing, while a larger rear sprocket lowers gearing. Similarly, a smaller front sprocket lowers the gearing while a smaller rear sprocket makes the gearing higher.

Chain and Sprocket Size Recommendation
Chain width becomes a problem on the X ring chains. You want to look for a "narrow" x-ring. X-rings are great for wet conditions, otherwise a standard chain is fine. Standard chains are easier to maintain since you can just blast them, fling the water out, and then lube them.
chains and sprockets- CRF 250X
Hi, After some research I bought a DID narrow X-ring chain. Called "520VT2 Enduro Racing" I suspect any other chain will rub on the crankcase as there is very little room between the front sprocket and the crankcase. It cost NZ$205 (around US$165. (Yes I know we are being ripped off here downunder). cheers, Peter
