Finally pulled the trigger and picked up brand spanking new WR450 tonight. I have had awesome CRF450X for years and it never let me down, but it was time for something new. Can't wait to break it in and try it at full song. I expect great things from this machine. Already got racing ECU and tuner, but want to break it in before uncorking it. Stay tuned for review and comparison to 450 X, I'm sure a lot of people are in my shoes. BTW I must say I'm very impressed by the crew over at Thousand Oaks Powersports. Normally dealers are associated with negative emotions, and these guys are quite the opposite. Great service and all smiles.
