I spent the afternoon riding with a guy on a 450r and I must say that he could beat me in the turns on open ground but in the woods there was no comparison.
In places where he would have to slow down and pick his way through the ruts, roots, and logs I would be on the throttle and going away. In places where the mud was a factor he was stuck and I was just driving through. ( I had to stop and wait for him or help him get unstuck)
Doing some hill climbs the 450r would have to pick a careful line to go up and the Outlaw would be way more forgiving of not so good choices.
P.S. this guy has way more experience riding sport quads than I do. He has years and I have 1 month.
