I have a YBR 125. I would like to upgrade to a 15t front sprocket for more top end speed. Now the problem I have is the chain. How many links should I buy the chain for this new sprocket. I know that the standard sprocket is 14t and the standard chain is 428 pitch and 118 links. Should I buy one with 1 link more?

Thanks

no...surely it will fit if you shove the wheel further forward?

just adjust your wheel to fit the chain you already have??
