Performance
Genesis 998 Turbo Four-Stroke
 The base of the Genesis 998T is the over-achieving Genesis triple. Already renowned for pulling consistently hard from take off 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 nine 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 four-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, lightweight, 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 high 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 chaincase 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 driveshaft, 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.  
15 x 129 x 1.25-inch Camoplast® Ripsaw™ II Track
 The Sidewinder R-TX SE uses the extraordinary Camoplast Ripsaw II track, measuring 15 x 129 inches, with 1.25-inch lugs. This evolutionary lightweight track design is the next stage of close collaboration between Yamaha and Camoplast. It features a durable single-ply design with next-generation lug pattern. The Ripsaw II has been designed to offer increased controlled lateral slide, allowing the Sidewinder to set up for the corner better while scrubbing off energy to keep both skis on the ground. The result is improved handling without the loss of straight line traction.  
Handling
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 bump steer 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 colors 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, center to center, 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 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 grip material as the main bar section, for consistent control, regardless of hand position on the grip.  
Comfort
Fox® 1.5 Zero™ RC Front Shock Absorbers
 These new coil-over shock absorbers have a three-way adjustable rebound damper and pre-load adjustable coil spring for improved bump compliance and no fade performance.   
Dual Shock SR129 Rear Suspension
 The Sidewinder R-TX SE's 1.5-inch center and rear 2-inch Monotube gas shocks give excellent suspension performance in stock trim.  
 With a 0.5-inch to slide freely under acceleration and deceleration, thanks to a unique front arm slotted mount design, the Dual Shock SR suspension keeps the track planted for maximum grip under full throttle or full braking.  
 The rear axle features a conjoined rear wheel-set. 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-liter 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.  
Tall, Sculpted Seat
 The seat foam on the Sidewinder is anatomically designed to comfortably put the rider in an aggressive posture with easy transitions from seated to standing to leaning into a corner.  
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 four-stroke machines.
