I'll start with the facts. Bike: 2008 CRF450R Weight: 175 w/o gear Skill: front-mid pack novice, motocross only (Int.-hardpack) I was at Club Moto today in Livermore, CA with DaveJ's new Duel Spring Del Taco design. I had Dave do the work, because I wanted it done right the first time. The stock suspension on the 08' CRF450R is great at taking big hits, but it beats you to death in the chop, square edge bumps. This new kit really made the ride very smooth, and I was very impressed. It still handles the big stuff the way it did before, but it soaked up the hack like never before. Just for the record I had Dave service and modify the shock too. For the price you just can't beat it. Some of my friends have spent a grip of money on their suspension, and in my opinion DaveJ's work is just as good or better in many cases. I rode out a full tank of fuel at the track today. I'm saying this, because I usually tire out before a full tank. This kit is impressive. Thanks Dave!
