I have the 450 currently in dirt mode. I really like this bike as a trail bike. It's a mountain of fun. I have fitted the map switch which I had forgotten to fit when it went in for the dyno and for the day at MVTC. Nevertheless I still don't think it would run with Dallas's YZ450. His felt stronger. That's a very competitive bike. Well done Dallas. Nevertheless the 450 is up there which is what I was aiming for. Just gotta get the geometry sorted on the bent Berg. I think I may have taken on something a little out over of the ordinary. All good fun.
