Conquer Snow

The X-TX 137 LE is perfect for riders in areas of abundant snow, groomed trails and open areas. Unlike our other X-TX models, it maintains the full 42inch ski stance of the trail models along with a coupled rear skid frame for excellent cornering manners. In the loose stuff, a 1.75 x 137 inch Back Country track helps throw down the massive power generated by the Genesis High Performance Turbo and the new Tuner 3 skis are hooked up with acclaimed, quick adjust Fox QS3 coil over shock absorbers. (Note: only available during our Spring Power Surge)

 Triple Throttle Bodies

  • Unique Yamaha Technology
  • Balanced Intake
  • Instant response
  Yamaha - Mitsubishi ECU

  • 9 sensor management system.
  • Integrated mapping
  • Responsive and reliable
   YSRC Primary Clutch

  • Stable RPM
  • Higher strength
  • Excellent V-belt durability
  • Genesis 998 Turbo 4-stroke

The base of the Genesis 998T is the over-achieving Genesis® triple. Already renowned for pulling consistently hard from takeoff to top end, the factory-installed Turbo takes it to next level status while maintaining Yamaha's reputation for quality, durability and reliability.

  • High Quality Turbo-Charger

The Nickel alloy turbine body is extremely strong and precise, able to withstand highly elevated temperatures. Supported by top grade, ceramic ball bearings, the Inconel turbine blade assembly is very light and strong

  • Yamaha-Mitsubishi ECU

The Yamaha Mitsubishi Electronic Control Unit (ECU) uses a series of 9 sensors to gather running condition data and computes using its predetermined memory 'map'. It then adjusts ignition timing, fuel delivery, manifold air-pressure and turbo boost pressure to produce maximum performance - reliably.

  • Triple Throttle Body Induction

Each cylinder has its own throttle body located as close as possible to the intake valves. This unique design offers immediate throttle response when combined with the efficient turbo and air bypass system.

  • ABV — Air Bypass Valve

Unlike regular blow-off valves, the ABV redirects air pressure back into the intake side of the compressor to prevent surge and maintain impeller speed, always at the ready for the next acceleration.

  • Liquid Cooled Turbo Body

Engine coolant is circulated through the turbocharger to control temperature. Upon engine shut down, the convection energy produced by super-heated coolant at the turbo 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.

  • Engine Braking Control

The effect of 4-stroke 'engine braking' when the throttle valves are closed has a significant impact on handling and ride character. Yamaha developed a special system which employs the ISC (idle speed control) circuit and ECU map using throttle valve movement and RPM information to reduce negative intake pressure during deceleration.

  • Coated Aluminum Cylinders

The lightweight aluminum block has ceramic composite plating applied directly to the cylinder wall to eliminate the need for a steel cylinder sleeve and in doing so ensures excellent abrasion resistance and cooling performance

  • Press Forged Crank Shaft

A specialized press method manufacturing process is adopted (forging process without twisting of the metal) to provide the needed strength to the crankshaft assembly to withstand the additional stress produced within a 'boosted' engine.

  • High Strength Connecting Rods

Special, light weight, hardened steel connecting rod design has the optimum strength required to produce maximum power. New 'carburized' steel connecting rod uses nutted studs to join the close tolerance, machined faced, big-end. Special 'Defric' coating applied for cold start protection and to maximize reliability.

  • Forged Pistons

The forged aluminum pistons are formed without melting the original aluminum stock, so they retain the strength of the original solidification structure, which enables the design of a lighter piston. This lightweight piston contributes to better 'pick-up' or 'response' while also reducing vibration.

  • Piston Cooling

The new engine features a unique piston oil cooling system. Oil is sprayed directly at the underside of the pistons through special jets to help cool and lubricate them.

  • Forged Cam Shafts

The Yamaha cam shaft is forged from a solid bar then machined to its final finish and a special heat treatment is applied. This produces a very lightweight and durable component capable of maintaining high RPMs.

  • Counter Balancer

The advantage of the reduction in vibration is realized in multiple benefits for both the vehicle and the operator adding greater running stability with less rider fatigue.

  • YSRC Roller Secondary Clutch

The new reverse cam secondary features roller cam followers to reduce friction and special hi efficiency casting designs to improve aerodynamic power loss and reduce temperature. Sheave casting strength is improved to handle the higher horsepower and drive ratio is increased for wider speed range allowing the use of lower final gears.

  • YSRC Primary Clutch

New 'YSRC' primary clutch is designed for high horsepower with greater Strength improved efficiency and enhanced cooling ability.

  • Fuel injection

Yamaha's advanced fuel injection system controls fuel flow to the engine for spot-on performance and throttle response.

  • Multi-purpose magnesium chaincase

The Sidewinder chain case and cover serve as both a mounting point for chassis spars and the engine's oil reservoir. Lightweight magnesium construction minimizes weight.

  • High performance Hayes Brake system

The Sidewinder's high performance Hayes brake system delivers stopping power with a large-diameter, 8-inch rotor. Mounted low on the drive shaft, you feel immediate whoa-power with a quick stab of the brake. The hydraulic brake's race-inspired radial master cylinder design gives you excellent leverage when needed, with precise brake feel and control.

  • 137x1.75x15 Back Country Track

The 1.75 lug Back Country track has a reputation for excellent durability on groomed trails along with impressive deep snow flotation. In the 137 length, it is a good choice for riders who get plenty of fresh snow on their local trails.

  • 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.

  • SRV Front suspension

The SRV front suspension geometry is aimed at managing spindle camber, resulting in minimized bumpsteer and maximized cornering bite and 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.

  • Centralized mass design

The SRV chassis layout was engineered with the goal of centralizing mass. Approximately 60 percent of the sled's weight is tightly centered within the main triangulation. The result is a quick-handling sled that's fun in a wide variety of conditions.

  • Gen3 Tuner Skis

The latest version of the Yamaha Tuner Ski is lighter and designed for improved 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 colours for additional customization.

  • Adjustable ski stance

The ski rubbers on the Sidewinder are asymmetrical, with a portion of the part serving as a spacer for the ski. This allows riders to adjust the ski stance on the Sidewinder from 42 to 43 inches, centre to centre, by simply switching the ski rubbers from left to right, and right to left.

  • Over-the-engine steering

The straight steering post on the Sidewinder is configured over the engine. It connects to a single bell crank for simplicity and light weight. The design also minimizes freeplay in the steering system and delivers a tight turning radius.

  • Tall, hooked Mountain handlebars

To match the Sidewinder's tall and forward riding position, a single-piece, dual-hooked handlebar is standard fare. The hooks have the same new grip material and thickness as the main bar section, for consistent control, regardless of hand position on the grip.

  • FOX 1.5 ZERO QS3 KASHIMA Front Suspension

These premium coil-over shocks feature a simple, easy to use, 3 way damping adjuster to quickly dial into changing trail conditions

  • Dual Shock SR137 Rear Suspension

The Sidewinder X-TX 1.5" gas Monotube centre and adjustable rear 2.0" Fox QS3 gas shocks give excellent suspension performance in stock trim.
With a half-inch to slide freely under acceleration and deceleration, thanks to a unique front arm slotted mount design, the Dual Shock SR suspension couples the shocks to keep the rear end planted for maximum grip under full throttle or full braking.
The rear axle features a conjoined rear wheelset. The ingenious design is lighter, more durable and more rigid than most traditional rear axle wheels.

  • Tapered tunnel design

The Sidewinder's two-piece, tapered tunnel gives you strength for the long haul and a tapered "fit" for enhanced leg comfort and overall ride positioning.

  • Large fuel tank

The Sidewinder's generous 37-litre fuel tank serves more purposes than just carrying a day's worth of fuel. It also cradles the battery and is the platform for the quick-release trail seat.

  • Heated Trail Seat

Ergonomically designed for excellent rider mobility and comfort, the addition of an electric heated seat pad gives extra comfort on those long days in the saddle.

  • Digital gauge

Full-featured and easy to read, the digital gauge displays critical information in a glance including speed, fuel level, trip mileage, tach and more. We even included a clock so you can watch the time fly.

  • Push button reverse

Convenient handlebar positioning makes getting in reverse easy with just the push of your thumb. A servo motor shifts the drivetrain into reverse simply and consistently.

  • Standard electric start

Yamaha's electric starter system allows consumers to fire up their Sidewinder with the turn of a key. There is no pulling on a nylon cord to get this high-tech engine growling! Electric start is a standard feature on all of Yamaha's 4-stroke machines.
