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 3rd party, DynoTech Research, easily saw 160 HP. Tha's 10% more HP 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 pounds, improving sidehill capabilities by moving the wheels inboard of the rails to increase track flexibility. The M Series Power Claw™ is a single-ply 153" 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" is the ultimate in mountain ergonomics and a force to be reckoned with.

Fox Float® Rear Skid: Torsion springs are history. This redesigned frame decreases unsprung weight and reduces unwanted track tensioning. Two rear-mounted wheels inside the rails increase track flexibility and improve sidehill capabilities. The rear end is dampened with a lightweight aluminum FOX® Zero Pro gas shock on the front arm and a FOX Float® shock on the rear arm.

H.O. 800 - The 800 engine is a 2-stroke, 794cc liquid twin with batteryless electronic fuel injection. An engine "laid down" in the chassis moves snowmobile mass toward the ground and effectively lowers the center of gravity. BEFI adjusts for temperature and altitude. In 2010, we've powered up every 800 engine for an increased 10% more HP over last year. An independent 3rd party, DynoTech Research, easily saw 160 HP. Engine reverse is also standard on the 800. There's also a new exhaust pipe, manifld, resonator and a lightweight crankshaft.

Engine Reverse: Push—button electronic reverse gets even better. As a feature of the engine, not only is it quick, it’s also a weight saver that sheds nearly 8 pounds.

153" Power Claw™ Track: The M Series Power Claw™ Track is nothing short of miraculous in the steep and deep and surprisingly well behaved on the trail. The 153" track is 15" wide with grabby 2.25" paddles.

Lightweight Running Boards: The running boards with diamond-shaped cutouts reduce weight, disperse snow and impove foot traction.

New Lightweight Seat: The new blow-molded seat base is 3.5 pounds lighter and 3 inches taller than the previous design, while the tapered shape improves maneuverability for both sitting and standing.
