"I had these on my 250f for a few years. One of my rims broke at the weld with less than ten hours. They replaced it. The spokes never set in. They came loose after every moto and my wheels went out of true extremely fast. I was unable to make them better. I now have Excel wheels on a Yz250 and they do not come loose. Spend the extra and get quality."

"I have used Renthal sprockets before. Once with a 250f and R1 chain, now with a 250 and DID ERT2 chain. ] Barely visible wear after one race and one practice day. The last set lasted me a looong time. Keep the chain tensioned correctly and it will do you good. Oh- and the ERT2 from DID is a better chain than the Renthal R1."
