The M series from Arctic Cat is manufactured to be King of the Hill with the highest horsepower rating of the 2010 sleds made for the mountains.

The 999cc engine hasn’t changed from 2009 models. With batteryless electronic fuel injection (EFI), the 90.3 x 70 bore and stroke twin-cylinder two-stroke engine delivers 162 HP at 7,250 – 7,300 rpm, along with 116-to 118-foot-pounds of torque.

Traction on the hill comes from a 15-inch wide Power Claw track — an 80 durometer, three-pitch track that has negative 20-degree paddles and traction towers that tilt a positive 20-degrees.
