I bought this KMC O-ring for my 250. I ran mid school kmc 415 chains with my bmx's growing up, never problems. So, naturally, I saw them later in my life offering a dirt bike version. So far I'm very pleased with the performance. Quiet, smooth. Last renthal chain I had, at low rpm climbing, chattered pretty good. So far, this one is smooth. I just recently bought a second one (a few links longer) due to changing my gear ratio. I bought other 520 pitch chains off eBay but they were 1/16" wider than KMC/PRO TAPER/RENTHAL. Didn't want to harm the bike. So far very satisfied
