Hello
I have a 500L. I bought mine this winter for plowing and had 0 problems plowing. Went through all snow. I went on 2 rides with it the last 2 weeks and put about 66 miles on it. It's great on trails went through mud without an issue (and I hit every mud run I could find). Water crossings were no problem had it over the headlights. Went to a place in PA last week and it had more rocks and boulder size rock climbing up a mountain without an issue. My only issue is I bottomed out a couple of times on some rocks pretty hard with the front skid plate. But I was running hard on the throttle.
From all the reviews I have read or watched the 500 has great mid to top end where as the 450 has great low to mid range.
Buy skid plates.
Hope this helps you. :th_smiliethumbsup:
