Which would you guys say is the best bike for tight boney trails. New England style. It's actually for my wife, shes 5'6" 130lbs. and very athletic. So I'm not afraid to get her one of these bikes. I'm leaning towards the xr for it's lack of radiators and I'm guessing threaded valve adjustments. I would be riding the bike too. I'm 185lbs. It's got to have enough snort to get her up any hill that I can climb on my DRZ. I may be dual sporting the bike so that is a consideration too. But I think the most important factors would be trail worth chasis, light weight, durability, low maintanence, crash damage resistance!
