I have an 03 CRF450R that I use for trail riding only. I am pretty happy with the way the suspension performs except on steep down hills. When trying to creep slowly down long, steep downhills and I apply the front and rear brakes the rear goes very high in the air. I am not even able to put my left foot down for balance. I am 6'4" and 250 lbs and even putting all my weight on the seat doesn't bring it down. I bought the bike 3 years ago with suspension set up by Factory Connection for 205lb A level motocross rider. It felt good otherwise so I never messed with it.
