Supper clean runs excellent has tons and tons of power. Has some mods to make it better for mountain riding. Has some bar risers with some renthal bars and some aftermarket grips. Has slp track extender with a longer track. Also has a tunnel cut to go along with the extended track. Has some Simmons skis along with it. It has an extra can to go along with it. Clean sled overall and just got a service where we went through all of it and changed the chain case oil and spark plugs. Love the sled but want to get into something newer. Also have another Mountain max 600 to go with it as a parts sled as well.
