I bought a 05 CRF450R a few days ago and went riding yesterday. I'm only about 135 pounds and I made the front suspension as soft as it would go with the clickers. It feels fine off of jumps but when I'm going down hill with a bunch of little bumps, it shakes me around the the suspension of my CRF230. Would you guys suggest me sending my suspension to some one or getting a different spring. I was also looking for that spring rate calculator some one had posted about a while back. The one where you tell your weight and what kind of riding you do. Any suggestions?
