I have been racing for over 20 years. I have been messing around with my 2010 yz450 for 6 months trying to get it right. Finally I tried the Ohlins fork and shock and I have to say this is the best it has ever been. I have finally gotten this bike the way I want it. The suspension is soooo plush its unbelievable. I really like the shock also, the bike is really calm.
