I've had it almost 2 months now, my teryx has muzzys, msd and all that jazz on it. It would do 68mph easy but I had about 15,000 into it. My rzr s is bone stock and it will do that fast easily, I love the motor alot better so far. The long travel is amazing too, sure I could have done it to my teryx but it would of been way too wide for the trails around here. I wanted a rzr before my teryx but wasn't too keen on them. But after I got my teryx abour 8 of my friends bought rzr, rzr 4 and rzr-s's and none of them have any problems at all. And some of them have up wards of 2000 miles and nothing so far. Its all about how you maintain something if you ask me. I liked the teryx for the dump bed and the bed space, the rzr seats are alot more comfortable and it rides alot better. It gets way better gas milage then my teryx did, I can ride forever on it. I paid 12,100 OTD for my 09 monster sport edition, then had roof, winch, windshield, radio, msd, muzzys, dalton od plate. I was up around 15,000 easily. My rzr I have less then that into it and I have windshield, roof, back window, bed extender, winch and radio. It rides better, came with big horns, more comfortable seats. The 2011 rzr has high and low beams and a glove box now so that made things nice. I mostly use my sxs on trails and for play, no work. If I used it around the house I would want a teryx hands down. RZR is nicer on the trails around here too because the roll cage isnt so tall and hitting off all the trees. It all comes down to personal opinion really. After owning a 04 rhino, 09 teryx and now a 11 rzr s. I fell like I've upgraded each time. Surely Id love a teryx thats long travel and a 840 I would not own a rzr but I also dont feel like having over 20,000$ into a sxs. That would buy me a nice diesel truck ha. I'm not trash talkin the teryx. Its all just personal opinion really and the rzr better suits my riding style. I have about 300 miles on my rzr now and not a single problem. I had 2060 miles on my teryx and only thing I did in those miles were front break pads and a left rear axle boot. The engine had been re ringed and I got a hole in my radiator twice. The 09 front bumper just scooped sticks right up into the radiator on that thing and they were my worst enemy.
