Hi, I bought a 2009 KX250F Monster Edition recently with very low hours, and it still has the stock chain and sprockets. The chain is pretty stretched now, I've only put about 2 hours on the bike since I got it and the difference is noticeable compared to when I bought it. I've read that people are going to a 13 / 49 sprocket setup so that's what I'm planning, but I would like some feedback on what sprockets and chain I should go with. I'm looking for an o-ring chain for lower maintenance, and I'd like it to be gold just because I find that looks good. Anyone have recommendations for fairly inexpensive, high quality chains that fit the above description? I was looking at the Gold RK 520xso rx-ring chain, anyone have experience with it? Also, I was thinking of Renthal Sprockets front and rear, 13 / 49. Anyone know how these hold up? Any recommendations for less expensive but just as good sprockets? So far I'm loving this bike! Thanks guys!
