TOP FEATURES

  1. 146 Dual Load Rear Suspension
    The Dualshock 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.
  2. Deluxe 2- Piece Heated King-Queen Seat
    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.
  3. Tether Switch
    An integrated switch automatically shuts-down the engine when ever the driver is not on-board.
  4. SRV Front Suspension
    The SRV front suspension geometry is aimed at managing spindle camber, resulting in minimized bump-steer and maximized cornering bit 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.
  5. Rear Hard Case With Auxiliary Fuel Tank
    You wont be caught short on a long ride with the convenient, moisture proof, hard storage case and 4 gallon auxiliary fuel tank. Total fuel capacity is bumped up to 11 gallons or 42 liters, which goes a long ways on the trail (and your peace of mind).

6. 998 Genesis Turbo Engine
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 industry's highest achiever. Truly this is the potent venom of a Sidewinder S-TX GT's bite.

PERFORMANCE

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.

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.

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.

HANDLING

EBRS 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.

146 x 1.25 in RipSaw™ 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.

HPG Shock Package
The Sidewinder S-TX GT receives a full compliment of proven, aluminum body HPG ( High Pressure Gas) shocks with 1.5" shock bodies offering fade free performance to handle all the challenges the trail can dish out.

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.

COMFORT

Multiple Accessory Power Plugs
Both driver and passenger are provided convenient RCA DC outlets for heated helmet visors plus a socket type outlet located in the console to power-up other 12V accessories.

Front/Rear Adjustable Hand Warmers
Both driver and passenger stay toasty warm with independently controlled hand warmers. The passenger also gets functional wind deflectors added to the padded rear grab bars to help keep the elements away from their hands.

Tall Wind Deflector
Escape the wind and winter chill with a sculpted, functional windshield. A small lip at the top deflects wind and snow up and over the rider at speed, while flared edges provide added protection and warmth for your hands.

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, pushbutton switch.

Stealth Control System
The handle bar controls feature a left hand switch cluster which allows for 'on the fly' access to the multi-step hand and thumb warmer adjusters. Information available on the multi-function gauge can be easily selected with a convenient 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 new composite Stealth brake lever provides great modulation for better feel and powerful stopping performance.
