2021 Yamaha Sidewinder L-TX SE

Comfort

• STEALTH CONTROL SYSTEM: The handlebar controls feature a left-sided switch cluster for “on-the-fly” access to the multi-step hand and thumb warm adjusters, the push button reverse gear shift and the multi-function gauge that can be easily select information with a convenient toggle. On the right side, a clean bar hosts an ergonomically-shaped throttle lever and a simple, stand-alone emergency stop switch. The Hayes 'Stealth' brake cylinder is equipped with a composite brake lever that, coupled with a lightweight caliper, offers better feel and powerful stopping performance.
• TAPERED TUNNEL DESIGN: The Sidewinder's light weight, two-piece, tapered tunnel enhances leg comfort and overall ride positioning during long hauls while the reinforced running boards are punched with aggressive boot hold serrations that offer excellent snow evacuation to keep your feet planted where you want them.
• HANDLEBAR-CONTROLLED DIGITAL GAUGE: Fully-featured and easy-to-read, the digital gauge displays critical information in a glance including speed, fuel level, trip mileage, tach, elevation, temperatures and more. Easily change functions with the switch controls on the left handle bar.
• PUSH BUTTON REVERSE: With just the push of your thumb, you can easily shift to and from reverse. A servo motor shifts the drivetrain into reverse simply and consistently while an audible warning beeper reminds you when the system is still in reverse.

Handling

• CENTRALIZED MASS DESIGN: The SRV chassis layout was engineered to centralize mass. Approximately 60% of the sled's weight is tightly centered within the main triangulation for 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 builds chassis strength without excessive weight.
• RIPSAW II TRACK: Regarded as the best high-performance terrain track available, the 151" x 1.25" RipSaw lug delivers incredible acceleration, braking control and handling in a wide variety of conditions.
• SINGLE KEEL SKI: The Yamaha-designed single keel ski strikes the elusive balance between lightweight steering effort and precision handling. Unique, staggered carbides further enhance steering response while the exclusive shim pad assembly works with the rubber saddle block to adjust the carbide pressure point. By relocating the thick spacer located on each ski axle to the opposite side, the ski stance becomes adjustable.
• OVER-THE-ENGINE STEERING: The straight steering post is configured over the engine and connects to a single bell crank for simplicity and a light weight which minimizes free-play in the steering system and delivers a tight turning radius.

Performance

• HIGH TECH TURBO: Able to withstand highly elevated temperatures, the Nickel alloy turbine body is extremely strong and precise. Supported by premium ceramic ball bearings, the Inconel turbine blade assembly is very light and strong which yields a low moment of inertia for a lightning quick response to the exhaust gas input. Triple throttle bodies are used exclusively to further enhance the quick delivery of compressed air from the impeller to the intake valves.
• MITSUBISHI ELECTRONIC CONTROL UNIT: The Yamaha-developed Mitsubishi ECU uses a series of 9 sensors to gather running condition data to compute a predetermined memory map which will adjusts ignition timing, fuel delivery, manifold air-pressure and turbo boost pressure to produce maximum performance under any condition.
• TRIPLE THROTTLE BODY INDUCTION: The Yamaha Genesis turbo engine's intake system uses three separate throttle bodies that are positioned very close to the intake valves to create a quick engine response with little to no lag. This is something not see in any other production turbo on the planet.
• 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 which prevents surge and maintains impeller speed.
• LIQUID COOLED TURBO BODY: When the engine shuts down, the convection energy produced by the super-heated coolant at the turbo head keeps circulating without the coolant pump in operation which eliminates the need for an engine cool down cycle, all while maintaining the turbo components' durability.

Top Features

• 998 GENESIS TURBO ENGINE: The 998 Genesis Turbo Engine is unmatched when it comes to delivering incredible power. Every engine component from intake to exhaust is dedicated to producing uncompromised performance, earning the respect and reputation as the industry's highest achiever.
• YSRC HIGH PERFORMANCE CLUTCH SYSTEM: The YSRC primary and roller secondary clutches are calibrated for durable, cool operation. They efficiently harness and transfer the massive torque produced by the Genesis Turbo to the track, all while minimizing drive belt wear. The primary shifts out aggressively to use all of the power while the roller secondary is quick to back-shift and provides additional ratio through its oversized sheaves for continuous acceleration.
• ENGINE BRAKING REDUCTION SYSTEM: The effect of 4-stroke 'engine braking' when the throttle valves are closed has a significant impact on handling and ride character, so Yamaha developed a special system which employs the ISC (idle speed control) circuit and ECU map that uses throttle valve movement and RPM information to reduce negative intake pressure during deceleration.
• ARCS FRONT SUSPENSION: The ARCS front suspension features tall, strong forged alloy spindles and redesigned lightweight upper A-arms. Revised for optimum suspension function and increased ground clearance, the Sidewinder L-TX SE has a more predictable and consistent handling with less chassis roll.
• DUAL SHOCK SR REAR SUSPENSION: The lightweight Dual Shock SR rear 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 ski-lift during acceleration while retaining a good measure of independent front arm tracking. The solid rear axle layout with its special idler wheel design and configuration provides great durability.
• SHOCK PACKAGE: The Special Edition comes with premium Fox Zero RC front shock absorbers with adjustable coil springs and a wide range of damping adjustments. These shocks include Fox FIST ice scraper technology, velocity sensitive damping and high quality hard chrome rods with T6 anodized 1.5" bodies. The skid frame front arm has an aluminum 1.5 HPG gas shock while the rear duties are carried out by a beefier 2.0 aluminum HPG shock for fade-free performance.
