I wouldn't put too much weight into what the boyz are saying at DIRT TRAX. About 5 episodes back they LIKED the 550.

Wifey's got one. Luvs it. Haven't had 1 issue in 400+ miles. It's got a ton on lowend and I found it to be pretty snappy in terms of throttle response.

She was pulling over-filled snomobile trailers of cut wood back to our "splitter" area about a wk ago through about 1/4 mile of VERY soft cultivated field. Threw it in L and 4whl.....NP.

I found it quite comparable to my TRV 650H1 carb'd for overall performance. It is noisy'r but that's due to the change in the transmission bevel gear update in '09.

Oh top end - 50+mph.
