Take that mountain with all the force you can muster. With the all-new EFI H.O. 800 2-stroke engine, it might even plead for mercy. An independent third-party, DynoTech Research, easily saw 160 hp. That's 10% more horsepower than last year. It's an expert-grade mountain sled, embodying a great combination of power, lightweight design and agility. The FOX Float® rear skid is expertly designed to decrease unsprung weight by 5.1 lbs., improving side hilling capabilities by moving the wheels inboard of the rails to increasing track flexibility. The M series Power Claw™ is a single-ply 153 in. track that has a habit of never letting you down. And the lightweight running boards not only disperse snow, but also improve foot traction in the process. Power and dependability. The M8 153 in. is the ultimate in mountain ergonomics and a force to be reckoned with.
