i rode polaris all my life then in spring of '06 my last poo burned down for about the 5th time and that was the final straw. got rid of that and picked up my first and so far only cat an '06 m7 and couldnt be happier been the funnest most reliable sled i've ever owned, even with all my dicking with it. only major thing i've HAD to replace was the primary clutch at about 2500 miles. i've rode all different brands and models and i will definately stick with the M.
