Features

Comfort

  • HEATED MOUNTAIN SEAT: The lightweight mountain seat's tall and narrow profile eases rider transitions from side-to-side and improves stand-up ergonomics. Plus, the electric heat elements adds additional comfort in the cold.
  • LARGE CAPACITY FUEL TANK: The Sidewinder's generous 8.9 gallon / 33.6 liter fuel tank serves more purpose than just carrying a day's worth of fuel. It also cradles the battery and is the platform for the quick-release trail seat. The ever-changing fuel load is carried low and rearward which helps centralize the overall mass and balance of the sled.
  • STEALTH CONTROL SYSTEM: The handlebar controls feature a left-sided switch cluster for “on-the-fly” access to the multi-step hand and thumb warm adjusters, the push button reverse gear shift and the multi-function gauge that can be easily select information with a convenient toggle. On the right side, a clean bar hosts an ergonomically-shaped throttle lever and a simple, stand-alone emergency stop switch. The Hayes 'Stealth' brake cylinder is equipped with a composite brake lever that, coupled with a lightweight caliper, offers better feel and powerful stopping performance.
  • 20" TUNNEL BAG: The under-seat bag provides additional storage. With it's semi-rigid design, the bag is easy-to-access and water resistant while the quarter-turn, quick-release fasteners make for a quick removal.
  • PUSH BUTTON REVERSE: With just the push of your thumb, you can easily shift to and from reverse. A servo motor shifts the drivetrain into reverse simply and consistently while an audible warning beeper reminds you when the system is still in reverse.

Handling

  • CENTRALIZED MASS DESIGN: The SRV chassis layout was engineered to centralize mass. Approximately 60% of the sled's weight is tightly centered within the main triangulation for a quick-handling, well-balanced sled that's fun to throw around in a wide variety of conditions.
  • LIGHTWEIGHT, RIGID SRV CHASSIS: The SRV chassis combines a load-bearing triangulated structure with lightweight aluminum construction to create a neutrally balanced sled that's centered on the rider. The pyramidal upper frame builds chassis strength without excessive weight.
  • 42" SKI STANCE: The full width ski stance is designed for aggressive corner speeds with flat handling characteristics.
  • MOUNTAIN STEERING SYSTEM: A dedicated, tall-steering post delivers optimum ergonomics for stand-up riding. The 5.5" riser and the broad, molded, curved-end mountain bar and incorporated mountain strap deliver ample leverage for off-trail riding. The adjustable system dials you in during sweep and reach to keep you in the sweet spot.
  • SINGLE KEEL SKI: The Yamaha-designed single keel ski strikes the elusive balance between lightweight steering effort and precision handling. Unique, tapered carbides further enhance steering response while the exclusive shim pad assembly works with the rubber saddle block to adjust the carbide pressure point. By relocating the thick spacer located on each ski axle to the opposite side, the ski stance becomes adjustable.

Performance

  • HIGH TECH TURBO: Able to withstand highly elevated temperatures, the Nickel alloy turbine body is extremely strong and precise. Supported by premium ceramic ball bearings, the Inconel turbine blade assembly is very light and strong which yields a low moment of inertia for a lightning quick response to the exhaust gas input. Triple throttle bodies are used exclusively to further enhance the quick delivery of compressed air from the impeller to the intake valves.
  • MITSUBISHI ELECTRONIC CONTROL UNIT: The Yamaha-developed Mitsubishi ECU uses a series of 9 sensors to gather running condition data to compute a predetermined memory map which will adjusts ignition timing, fuel delivery, manifold air-pressure and turbo boost pressure to produce maximum performance under any condition.
  • TRIPLE THROTTLE BODY INDUCTION: The Yamaha Genesis turbo engine's intake system uses three separate throttle bodies that are positioned very close to the intake valves to create a quick engine response with little to no lag. This is something not see in any other production turbo on the planet.
  • DUAL-PISTON BRAKING: A dual-piston brake caliper applies braking forces directly to the drive shaft with a wave-style, lightweight drilled rotor. The LE-only rotor removes 1 lb. of rotating mass from the vehicles driveline which transfers all of the Sidewinder's available horsepower to the snow. The Stealth master cylinder and composite Stealth brake lever offer excellent modulation and ergonomically precise operation.
  • ELECTRONIC AIR BYPASS VALVE (ABV): Unlike conventional turbo 'blow-off' valves, the Yamaha ABV redirects air pressure back into the intake side of the compressor which prevents surge and maintains impeller speed.
  • LIQUID COOLED TURBO BODY: When the engine shuts down, the convection energy produced by the super-heated coolant at the turbo head keeps circulating without the coolant pump in operation which eliminates the need for an engine cool down cycle, all while maintaining the turbo components' durability.

Top Features

  • 998 GENESIS TURBO ENGINE: The 998 Genesis Turbo Engine is unmatched when it comes to delivering incredible power. Every engine component from intake to exhaust is dedicated to producing uncompromised performance, earning the respect and reputation as the industry's highest achiever.
  • PREMIUM FOX® 1.5 QS3 FRONT SHOCKS: The Fox 1.5 Zero QS3, coil spring, high-pressure gas shocks feature a piggyback chamber that delivers reduced fading, exceptional control and three easy ways to adjust the compression damping performance settings, so you can quickly and easily adjust the ride based on the conditions and your riding preference.
  • VERRATTI 146 REAR SUSPENSION: The Dual Shock 146 rear suspension is fitted into a light mountain, tapered tunnel. It also features a mountain style front arm with special 146" rails that utilize a long rear QS3 shock with a lightweight single pull rod. The uniquely designed shock pivot on the uncoupled front arm provides a smooth transfer for great handling both in and out of the powder.
  • 146" X 1.6" COBRA™ TRACK: Blending the best of on-trail bite and off-trail flotation and traction, the 146" x 1.6" lug Cobra™ track is a key contributor to X-TX LE versatile make-up. The 146 length combined with the unique Cobra lug pattern give the X-TX the right balance between cornering grip and straight line acceleration, even in deep snow.
  • ARCS FRONT SUSPENSION: The ARCS front suspension features tall, strong forged alloy spindles and redesigned lightweight upper A-arms. Revised for optimum suspension function and increased ground clearance, the Sidewinder X-TX LE has a more predictable and consistent handling with less chassis roll.
