Looking at getting a new bike...Just curious how a newer WR450f would perform in the rocky trails located in SW Missouri and NW Arkansas (i.e., Chadwick, White Rock, Wolf Pen Gap)? The bike would be used for trail riding/racing with my friends on weekend trips. I've ridden all the new KTM 250/300 XCWs and the 400/450 EXCs at a recent Demo Day. All were very nice...might have to adjust the suspension, but that was it. However, pricing and availibility might keep me from going orange. I've always respected the big Yamaha. Everyone seems to love their WRs and the reliability is very impressive. I just thought I'd throw this question past the crowd to see what others have experienced. How does the Yamaha do in the rocky tight trails of the Ozarks? BTW...I'm 35 years old, been riding ~ five years, 6' and 210 lbs. Many thanks!!!
