I hear a lot of folks love their Arctic Cats. 100% positive responsed on similar posts on other sites.
I had a Bayou 300 that I couldn't keep a front drive shaft in...at $300 per pop.
I traded it in on a Yamaha. If I find a better, tougher and more reliable one I may just buy it on the spot. 6 years and never put a wrench to it except for routine maintenance and brakes.
