I'm looking at getting a new bike next spring and I'm strongly considering the 2006 Yamaha WR450F. The bike seems to get great reviews (both here and in magazines). However, I see more of these bikes being ridden in a West Coast setting. I understand that the bigger bikes are more suitable for open trail/desert. How do these bikes do in more of a East Coast setting? I would like to hear from folks who ride East of the Mississippi. How does your WR treat you? What does it do well and what are it's weak spots? FYI...I'm 35 (ridding for 8 years). 6'1" and 210lbs. Riding in and around Missouri offers a wide variety of trails (open, tight, muddy, dusty, hilly, rocky, etc). Many thanks!!!
