I have to go against the norm here dirt bikes are way more dangerous!!! I have raced MTN bikes since 89 and never had a really serious injury. I have run some of the nastiest downhills both nationals and worlds, but Jumping huge doubles on a dirt bike and ripping down single track at 70+ gets the pucker factor way up. I feel more comfortable jumping a 40' double on my downhill bike than the 426. With a MTB if things go bad you can just let go, and you don't have to worry about 260 lbs coming down on you. Also no matter how hard I try, I haven't been able to break the 65mph mark on my bike, on the WR all I have to do is twist the throttle. Can you smack a tree at 75-80 on a MTB, I think it would be hard. Bigdesto, I live in a weight weenie town all I hear is how real bikers ride up and that climb is Bitchen. So I just smile and think to my self: If they don't know the feeling they will never understand! Right bman.
