This sled may just transform you. To the point where you might not know where your body ends and the M8 162” Sno Pro® begins. This Expert-Grade Mountain Sled equipped has an all-new lightweight H.O. 800 laydown engine. An independent 3rd party, DynoTech Research, easily saw 160 HP. Thats 10% more HP than last year. The double whammy of this sled is the cooperation of FOX Float® ski shocks and a FOX Float rear skid. This power combo represents the perfect marriage of sleek design and cutting-edge technology that allow for a flawless trail ride. And a 162 single-ply Power CLaw™ track makes sure that your ride is on the up-and-up. The traction of its 15” wide track may make you forget the snowmobiles of your past. And what's function without comfort? Telescoping handlebar adjusts for your riding style and a new lightweight seat is like sitting in your favorite armchair. Its tailored to you, the man within the machine 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. 162" 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 162" 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.
