This is a history-making sled. The Worlds Fastest 4-stroke snowmobile with a longer track. The most powerful production engine in snowmobile history. 177 horses push you forward with blinding speed and 121 feet pounds of torque at 7,300 rpm guiding you along your journey is the added bonus of a 144 by 15 by 1.25 inch single-ply Cobra track, a light and freerolling tool for incredible traction no matter where you decide to blaze a trail. The ultra rigid Twin Spar chassis braves the elements with suspension that makes the most of our Body-Saving Ride Technology in the process. This is quite possibly the greats marriage of power performance and comfort, all in one speed-hungry package.
