Features6000 2-Stroke Engine: This 599cc 2-stroke Dual-Stage Injection (DSI) C-TEC2™ power mill kicks out 125-class horsepower and is the product of a world-class engine assembly plant – ours. The electronic oil pump can accurately meter fuel/oil ratios not only by RPM, but also by altitude, dramatically reducing oil and fuel consumption. Whether you’re riding a ZR an M or a Crossover, the 6000 is one of the most satisfying engines ever to be cradled in the belly of a snowmobile.Arctic Race Front Suspension: Arctic race front suspension geometry was developed through racing. Our uniquely wide A-arm spacing complements the chassis design, which allows us to maintain a tighter suspension. And the new FOX® QS3 shocks let you adjust your shocks to suit the riding conditions without removing your gloves. Set the clicker to 1 for a smooth, comfortable ride like the LXR. Click it up a notch to setting 2, and you’ll straighten out the corners like a Sno Pro®. Or click up to number 3 to go head to head with an RR. These shocks have a premium coil over design with forged aluminum reservoir.SLIDE-ACTION Rear Suspension: The SLIDE-ACTION Rear Suspension brings race day technology to everyday riding. Our U-shaped slot fits over a fixed shaft to allow a crucial half-inch of sliding movement. As the rear transfer blocks are engaged, the free-acting front arm follows the terrain, keeping your skis firmly planted over bumps, and during aggressive cornering and acceleration. This significant detail controls ski lift during acceleration.
