Sidewinder X-TX LE 146

Don't let the snowy terrain stop you from getting where you want to be. Spring Power Surge Exclusive.

TOP FEATURES

1. 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 proven Yamaha turbo has earned the respect and reputation befitting the industry's highest achiever. This engine produces the potent venom in the Sidewinder XTX LE 146's bite.
2. Tether Switch
   An integrated switch automatically shuts-down the engine when ever the driver is not on-board.
3. Premium Fox® 1.5 QS3 Front Shocks
   The Sidewinder X-TX LE front suspension is equipped with Fox QS3 shocks for a premium upgrade to this model. The FOX high-pressure gas, coil spring shock features a piggyback chamber to deliver reduced fading, exceptional control, and three easy to adjust compression damping performance settings so you can quickly and easily adjust the ride to conditions and riding preference.
4. Versattak 146 Rear Suspension
   The NEW Dual Shock 146 rear suspension is designed around a light mountain, tapered tunnel. It also features a mountain style front arm with new 146" rails and utilizes a longer rear QS3 shock length with a lightweight single pull rod. A newly designed shock pivot is added to the uncoupled front arm to provide smooth transfer for great handling both in and out of the powder.
5. NEW 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 Sidewinder XTX LE 146's versatile make-up. The 146 length combined with the unique Cobra lug pattern give the Sidewinder X-TX LE 146 a good balance between cornering grip and straight line acceleration with excellent deep snow flotation.

6. NEW ARCS Front Suspension
The new Advanced Roll Center Suspension (ARCS) features taller, high strength, forged alloy spindles and redesigned lightweight upper 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.

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.

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.

Mountain Steering System
A dedicated, tall steering post delivers optimum ergonomics for standup riding. The 5.5" riser, with broad, molded, curved-end mountain bar and incorporated mountain strap delivers ample leverage for off-trail riding. The system is adjustable to dial in sweep and reach to help keep you in the sweet spot.

6.5" Crossover Skis
The Sidewinder X-TX LE 146 receives a new lightweight, single keel ski designed for deep snow floatation with precise handling traits in a wide variety of conditions including hard pack and groomed trail.

COMFORT

Heated Mountain Seat
Lightweight, with a tall and narrow profile, the Sidewinder X-TX LE 146 mountain seat is both shorter and more tapered towards the front than our standard trail seat. This allows for easier rider transitions from side-to-side, and improved stand-up ergonomics. Included in-seat electric heat element for additional comfort in the cold and wet.

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.

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.

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.

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.
