Feature Benefits

Top Features

  • 998 Genesis Turbo Engine
    The boosted, one liter triple is unmatched when it comes to delivering incredible power with the refinement and quality you have come to expect from a Yamaha. Designed around a premium turbo unit, every engine component from the pressed forged crank to the cast steel exhaust manifold is dedicated to producing uncompromised performance. The proven Yamaha engine has earned the respect and reputation befitting the industries highest achiever. This engine produces the potent venom in the Sidewinder L-TX LE's bite.
  • Tether Switch
    An integrated switch automatically shuts-down the engine when ever the driver is not on-board.
  • YSRC High Performance Clutch System
    The YSRC primary and roller secondary clutches are calibrated for durable, cool operation. They harness and transfer the massive torque produced by the Genesis Turbo efficiently to the track while minimizing drive belt wear. The primary shifts out aggressively to use all the power on tap while the roller secondary is quick to back-shift and provides additional ratio through its oversize sheaves. The result is continuous acceleration after others have signed off.
  • NEW ARCS Front Suspension
    The new Advanced Roll Center Suspension (ARCS) features taller, high-strength, forged alloy spindles and redesigned lightweight upper A-arms. The geometry is further revised to optimize suspension function while increasing ground clearance. This results in greater bite with less chassis roll for more predictable and consistent handling.
  • Fox® Zero iQS Shock Package
    FOX Intelligent Quick Shift (iQS) shock absorbers are employed up front and on the rear arm. Suspension can be adjusted electronically on the fly, using a left hand mounted switch on the bars. Compression damping is offered in three very noticeable steps from soft to firm. Once activated the SCU (suspension control unit), located on the shock body, alters the oil flow within all applicable shocks in less than one second allowing the rider to dial in suspension feel to the running conditions. The shock setting is clearly displayed in the left side digital gauge once the selection is made. Rebound damping is preset, remaining constant to control kick-back and 'packing' in the rough, regardless of the iQS compression selection.
  • Dual Shock SR 137 Rear Suspension
    The Dual Shock SR rear suspension is the cumulative result of years of punishment and development in snocross and cross-country competition. This lightweight suspension offers premium bump compliance with excellent resistance to bottoming. The Dual Shock SR is a “coupled” skid-frame that utilizes a unique “sliding” front arm mount with half an inch of movement at the front arm “slot”. This active arm design delivers controlled (reduced) ski-lift during acceleration while retaining a good measure of independent front arm tracking. A solid rear axle layout with special idler wheel design and configuration provides great durability.
  • 137 x 1.25 Ripsaw II Track
    The second generation Ripsaw track is known for its excellent cornering grip and all around handling prowess on groomed trails. The aggressive 1.25" lugs will bite into hard-pack keeping side slip at bay and still generate plenty of forward propulsion when things get soft.

Performance

  • High Tech Turbo
    The Nickel alloy turbine body is extremely strong and precise, able to withstand highly elevated temperatures. Supported by premium, ceramic ball bearings, the Inconel turbine blade assembly is very light and strong. This yields a low moment of inertia for lightning quick response to exhaust gas input. Triple throttle bodies are used exclusively to further enhance the quick delivery of compressed air from the impeller to intake valves.
  • Mitsubishi Electronic Control Unit
    The Yamaha-developed Mitsubishi ECU uses a series of 9 sensors to gather running condition data which it computes using a predetermined memory ‘map’. It then adjusts ignition timing, fuel delivery, manifold air-pressure and turbo boost pressure to produce maximum performance under any condition - reliably.
  • Triple Throttle Body Induction
    Yamaha wanted an engine that's exceptionally quick to respond with little or no 'lag' as found in a conventional turbo. One of the ways they achieved their goal was to develop an intake system using three separate throttle bodies positioned very close to the intake valves. Instead of just one feeding long intake tubes — something that is not seen in any other production turbo on the planet. And another first for Yamaha with the Genesis turbo.
  • 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 to prevent surge and help maintain impeller speed, always at the ready for the next acceleration with seamless power delivery.
  • Liquid Cooled Turbo Body
    Engine coolant is circulated through the turbocharger to control both under-hood temperature and help cool the intake charge. Upon engine shut down, the convection energy produced by super-heated coolant at the turbo head keeps it circulating without the coolant pump in operation. This eliminates the need for an engine cool down cycle while maintaining high durability in the turbo components.

Handling

  • Centralized Mass Design
    The SRV chassis layout was engineered with the goal of centralizing mass. Approximately 60% of the sled's weight is tightly centered within the main triangulation. The result is a quick-handling, well balanced sled, that's fun to throw around in a wide variety of conditions.
  • SRV Front Suspension
    The SRV front suspension geometry is aimed at managing spindle camber, resulting in minimized bump-steer and maximized cornering bite giving rider confidence in varying trail conditions. The A-arms are mounted at a 30-degree angle from the sled's centerline to efficiently dissipate impact force throughout the entire chassis. Likewise, the front shocks mount directly to the leading spar so that trail forces are routed to the strongest part of the chassis. Wide A-arm spacing minimizes flex and stress in the front suspension system, which means consistent and confident corner handling.
  • 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 creates chassis strength without excessive weight.
  • Gen3 Tuner Skis
    The latest version of the Yamaha Tuner Ski is lightweight and designed for precise handling response. A wide selection of carbides can be combined to dial the Tuner to fit any riding style. Replaceable ski tips are available in multiple colors for additional customization.
  • Over-The-Engine Steering
    The straight steering post on the Sidewinder L-TX LE is configured over the engine. It connects to a single bell crank for simplicity and light weight. The design also minimizes free-play in the steering system and delivers a tight turning radius.

Comfort

  • Tapered Tunnel Design
    The Sidewinder L-TX LE's light weight, two-piece, tapered tunnel gives you strength for the long haul and a tapered "fit" for enhanced leg comfort and overall ride positioning. The reinforced running boards are punched with aggressive boot hold serrations and offers excellent snow evacuation to keep your feet planted where you want them.
  • Heated Trail Seat
    A standard heated seat provides the ultimate in warmth and comfort on even the coldest of winter days. A simple flip of the dash-mounted switch allows you to choose from two settings of warmth allowing you to explore what lies beyond that next curve from sun-up to sundown in complete comfort.
  • Stealth Control System
    The handle bar controls feature a left hand switch cluster which allows for 'on the fly' access to the IQS electronic suspension adjustments along with multi-step hand and thumb warmer adjusters. Information available on the multi-function gauge can be easily selected with a toggle switch and the push button reverse gear switch is also located in the left hand cluster. The right side of the bar is clean with an ergonomically shaped throttle lever and simple, stand-alone emergency stop switch. An updated Hayes Stealth brake cylinder equipped with a composite Stealth brake lever provides greater modulation for better feel and powerful stopping performance.
  • Push Button Reverse
    Convenient handlebar positioning makes shifting to and from reverse easy with just the push of your thumb. A servo motor shifts the drivetrain into reverse simply and consistently. An audible warning beeper reminds you when you are still in reverse.
  • Push Button Electric Start
    As with all Yamaha 4-stroke powered snowmobiles, there is no need to pull on a string to bring the engine to life. Easy electric starting is achieved through a simple handlebar mounted, glove friendly, push-button switch.
  • 20" Tunnel Bag
    Additional storage is provided by a convenient new under-seat bag. It's semi-rigid design makes it easy to access and is water resistant to keep your spares safe and dry.
