First question: It's an O-ring chain. Did a 2003 KDX200 come with an O-Ring? That'll tell me the PO changed the chain since I know the sprockets have been changed; 13/45 on there now with very new teeth.
Second question: 45 on the back, smaller circumference means less chain needed right? Should I stick with the 520/108 and if so will that leave me with less adjustment room?
Feel free to recommend some chains: stick with O or go X?
Thanks!
