This is a history-making sled, The World's 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 ft-lbs. of torque at 7300 R.P.M. Guiding you along your journey is the added bonus of a 144" x 15" x 1.25" single-ply Cobra™ track, a light and free-rolling 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 Technology in the process. This is quite possibly the greatest marriage of power, performance and comfort, all in one speed-hungry package.


Slide-Action Rear Suspension™: Straight from the Sno Pro® race sled. Slide-Action Rear Suspension™ incorporates a U—shaped front arm slot that fits over a shaft bolted across the tunnel. This creates a half—inch of "sliding" movement, preventing the front arm from torque locking. Better still, it helps keep the skis planted during acceleration, all but eliminating ski lift when gassing it through the corners.


4-Stroke Z1 Turbo Engine: The 4-stroke, 1056 twin with electronic fuel injection was already perfect, but we added an inter-cooled turbocharger. The net effect is nothing short of jaw-dropping. A reliable engine that won't lose power at high elevation. So if you want the highest horsepower in the industry, this is your engine.


Twin Spar™ Chassis: Designed and manufactured to be incredibly rigid, the Twin Spar™ chassis employs two box-aluminum spars triangulated with the steering supports and tunnel spars. Self—piercing rivet construction ensures joint rigidity and long—lasting strength. The Twin Spar chassis places you in the perfect neutral riding position. With a taller seat and handlebar location, this position maximizes comfort and control in all riding conditions.


144" x 15" x 1.25" Cobra™ Track - When you want the benefits of a long track and a smooth 4-stroke, the Z1™ Turbo EXT fits the bill with its 144" x 15" x 1.25" Cobra™ Track


Infinite Rider Positioning™: The adjustable handlebar lets you fine your ideal riding position. Pair IRP™ with the Twin Spart™ chassis and you can fine-tune the riding position to maximize comfort and control in all riding conditions.


New Twin Spar™ Rear End: Our Twin Spar™ chassis’ rear end went through a little modification. Or beautification, whichever you prefer. We’ve removed the rear plastic trunk and added a new tunnel design. We also added a new LED taillight, snowflap and rear bumper. It’s definitely one hot—looking chassis.
