Is a 12 tooth front considered too small?
What negative affects, aside from quicker wear, could be caused by the smaller front?
I ask, because I have just put 12/45 gearing on my DRZ400. It came with 14/45, which I found far too tall for the tight stuff I like to ride. 12/45 feels good, and I reckon 13/50 would be perfect.
Cheers,
Glenn
