I thought I would share my views of the CRF450 after riding and maintaining it for a month. Power- Smooth and strong. The power comes on low and pulls hard. It doesn't have a hit like the 426; some like that, some dont. Suspension- For MX I went slowed rebound down 2 clicks and softened suspension 2 clicks. For woods I like the rebound the same but softened 2 more clicks (from my MX setting). I have left the shock alone. With these settings I am using all of the suspension. It has been soaking up everything I throw at it. A guy with a '01 CR250 w/Pro-Action suspension said it feels 10 times better than his. Turning- I have never had a problem turning this bike. The front end feels long when pushing the bike around the yard but I don't feel it when riding. Wrenching- Maintanence has been nothing but oil changes and clean oil filters. After a couple rides the chain needed tightened and some spokes were loose, nothing out of the ordinary though. The only changes I have made are CR High bars (although CR Mid will be my next choice) and handguards. I raced it in a HS race this weekend and have nothing but good things to say. I felt better after the 2 hour race than I ever did on my 250 or 650.
