High Performance Genesis 4-stroke engine The over-achieving Genesis® engine is the heart of our lightweight and aggressive SRViper model family. It pulls consistently hard from takeoff to top end. Your thumb cracks a trio of 41mm throttle bodies that deliver strong performance from idle to wide open.
Fuel injection The Genesis High Performance engine uses Yamaha’s advanced fuel injection system to control fuel flow to the engine. Consumers will enjoy the engine’s spot-on performance and throttle response as a result of the advanced electronic fuel injection system.
Engine braking reduction system The Genesis High Performance engine features the unique Engine Braking Reduction System. The system allows a small amount of air to pass through the fuel injection system when the throttle is released, giving riders a “coast” feeling.
Legendary Yamaha Clutching The SRViper S-TX DX uses the legendary Yamaha YVXC clutching. Easily the most reliable and durable clutch system in the industry, the YVXC has evolved to efficiently handle the unique power characteristics of the Genesis 4-stroke engine.
Multi-purpose magnesium chaincase The SRViper S-TX DX’s chain case 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 SRViper S-TX DX’s high performance Hayes brake system delivers stopping power with a large-diameter, 8-inch rotor. Mounted low on the drive shaft, 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 141 x 1.352-inch Camoplast® Cobra™ track The SRViper S-TX DX uses the Camoplast® Cobra™ track, measuring 15 by 141 inches, with 1.352-inch lugs. This lightweight track features a 3-inch pitch design with cupped lugs for excellent deep snow performance without compromising on-trail action. The durable, yet lightweight single-ply design offers performance and efficiency.
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 bumpsteer 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.
Side exit exhaust The exhaust exits out the belly on the SRVipers. The unique chassis layout allows the exhaust to exit the back of the engine, have the 3-into-1 manifold cooled by snow kicked up through a hole in the tunnel and then bring the pipe back to the muffler in a traditional configuration. The end result is mass centralization, excellent handling and consistent performance.
Adjustable ski stance The ski rubbers on the SRViper S-TX DX 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 SRViper S-TX DX 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 SRViper S-TX DX 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.
NEW! Deep-Keel Tuner ski ski The new Deep-Keel Tuner ski greatly contributes to the SRViper’s trail character. The new deep keel design is specifically developed to work with the SRViper models to keep the ski tracking straight and true down the trail, virtually eliminating nosiness and darting. Each keel has its own wearbar, and Yamaha has four different bar configurations to choose from, which means you can tune your sled's cornering bite and steering effort to suit your personal preference.
Tall, hooked handlebars with center strap To match the SRViper S-TX DX’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. The SRViper S-TX DX also sports a tough center grab strap for additional leverage options when the adventure heads into deep snow.
Comfort-tuned HPG shock package The SRViper S-TX DX is calibrated for all-day comfort and high mileage adventures. Coil springs over the rebuildable, comfort-tuned HPG shocks add a smoothing action over chattered-out trails.
Dual Shock SR 141 rear suspension The uncoupled Dual Shock SR 141 features a Fox FLOAT3 air shock on the rear arm, combined with aluminum-body HPG shock for maximum control and ride comfort regardless of whether you’re riding on or off trail. The rear axle features a conjoined rear wheelset. The ingenious design is lighter, more durable and more rigid than most traditional rear axle wheels.
Tapered tunnel design The SRViper X-TX SE’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 SRViper S-TX DX’s generous 10.6-gallon fuel tank combines with the Genesis engine’s acknowledged fuel efficiency to keep you on the trail longer. The SRViper S-TX DX’s efficient design philosophy means that even the fuel tank serves multiple functions. Not only does it carry gas for a long day on the trail, but it also cradles the battery and is the platform for the quick-release trail seat.
Tall, sculpted seat The seat foam on the SRViper S-TX DX 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.
Midheight windshield The SRViper S-TX DX’s windshield was designed to be as functional as it is stylish. It features a tall height with precisely engineered curvatures providing maximum protection from wind and swirl-in, with minimum aerodynamic drag,
Standard electric start Yamaha’s electric starter system allows consumers to fire up their SRViper S-TX DX’s 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 4-stroke machines.
