Not a head to head but ran into somebody(the only other rider on lake)while on a soda run and he just started talking to me like we were old friends. He wanted to ride around with someone. I reluctantly agreed just for a little while because parts for other sled came in and wanted to work on it. After about 15 min or so, he wants to trade sleds for a little bit. I said ok so were riding around what a piece of junk sled his was. It was a 2008 MXZ. I never rode a sled that new, thats why I traded. I don't know what those have for motors but the thing was slow, like embarassingly slow. The thing had a horrible darting problem too. I noticed the windshield was cracked and the gauges didnt work. We traded back and after my excuse to go home, I asked about the problems I noticed. He said just before I met up with him, he rolled it over, in reverse! He said the ski caught something. Since then no gauges or tail/brake light. I asked him why it was so slow(in nicer words) and he says what? slow? this thing flies! The whole time hes telling me about how fast it is, I kept thinking, I let this guy who I don't know from a hole in the ground ride my sled who just rolled his? He did ride mine nice but you have to with the lake conditions. Never doing that again. Never rode a sled that darted so bad. Not even the wildcat when it was toed out 2 1/2". I wanted to peek underneath but that would invite more conversation but I bet springs were set way tight on front of skid because the skis were as tight as they go. Are those things 440s? Rotax something ss it said on hood. Those must be considered touring sleds. Just a little story while its after 5am and I can't sleep. It ran good so it must just have a small motor or something.
