Bring your A-game when you prepare to take that mountain. With an all-new EFI H.O. 800 2-stroke engine. An independent 3rd party, DynoTech Research, easily saw 160 HP. Thats 10% more HP than last year. An unbeatable combination of power and performance. And on a wintry mountaintop, the quick start and great fuel economy means a lot. The M8 153" is 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 sidehilling capabilities while increasing track flexibility. And the single-ply 153" Power Claw™ track hammers through the deepest big-mountain powder. Yet another Expert-Grade Feature to add to the list when you're looking to improve your mountain prowess.
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.
FOX Float® Ski Shocks - Gives you the ultimate in suspension performance. The shocks utilize FOX's quick-adjust, load-optimizing air technology and are up to 6 pounds lighter than the conventional coil-over shocks.
Telescoping Handlebar: Our Mountain handlebar gets a new telescoping steering system that creates up-and-down adjustablity without adding extra weight. Drop it down on the trail. Raise it up in the powder. The telescoping handlebar features easy one-hand adjustment with 12 positions.
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.
