SIDEWINDER S-TX GT
Sidewinder S-TX GT produces the most power ever offered in a Yamaha 2-up machine. It absolutely blurs the line between a sporty trail touring package and all out lake-racer. Powered by the mighty Yamaha Genesis 998 turbo, this fully featured flag-ship cruiser stands above all other passenger capable snowmobiles. Extended fuel range, storage capacity for two, plus all the comfort and warmth you'd expect from a luxury sled are a given. Rocket past your buddy's racy big twin with turbo-charged authority. |

- The Dual Shock SR 146 offers a long profile version of our acclaimed trail comfort suspension. This lightweight suspension offers premium bump compliance with excellent resistance to bottoming. The Dual Shock SR 146 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. The addition of passenger 'overload' springs help compensate for the extra weight of a passenger to reduce bottoming and maintain balance.
- A plush 2-up 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 and your passenger has their own controls. The passenger also gets a fully adjustable backrest.
- 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.
- You wont be caught short on a long ride with the convenient, moisture proof, hard storage case and 4 usg / 16 liter auxiliary fuel tank. Total fuel capacity is bumped up to 13 usg / 50 liters, which goes a long ways on the trail (and your peace of mind).
- The turbo 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 intake to exhaust, is dedicated to producing uncompromised performance. The Yamaha turbo has earned the respect and reputation befitting the industries highest achiever. Truly this is the potent venom of a Sidewinders bite.

Performance
|
- 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.
- 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.
- 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.
- 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.

Handling
|
- 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.
- Regarded as the best high-performance terrain track available, the 146 inch x 1.25-inch lug design of the RipSaw delivers incredible acceleration, braking control, and handling in a wide variety of conditions.
- The Sidewinder S-TX GT sports front Fox QS3 adjustable shocks up front and aluminum body HPG ( High Pressure Gas) shocks in the rear, offering fade free performance to handle all the challenges the trail can dish out.
- The new Yamaha design, single keel ski, strikes the elusive balance between lightweight steering effort and precision handling over a wide range of snow conditions. Unique, tapered carbides further enhance steering response. A unique shim pad assembly works in conjunction with the rubber saddle block to adjust the carbide pressure point. Overall ski stance is also adjustable by relocating the thick spacer located on each ski axle to the opposite side.
