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 SR Vipers. 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 146 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 Viper from 42 to 43 inches, center to center, by simply switching the ski rubbers from left to right, and right to left.
The straight steering post on the SRViper S-TX 146 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.
Deep-Keel Tuner ski
The deep-Keel Tuner ski greatly contributes to the SRViper's trail character. The 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 wear-bar, 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
To match the SRViper S-TX 146 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.
HPG Coil-Over Front Shocks
High Pressure Gas (HPG) shocks with strong 40mm bodies are calibrated to deliver consistent performance and comfort with excellent fade resistance. Plus the shocks are rebuildable, ensuring you season after season of consistent performance with proper maintenance.
HPG Rear Shocks
Premium High Pressure Gas shocks are found at both the front and rear arms of the rear suspension - tuned for premium control and comfort with incredible fade resistance. The shocks are also serviceable, allowing your authorized Yamaha dealer to recharge and refresh them for consistent performance season after season.
Dual Shock SR 146 Rear Suspension
Based off the proven design of the SR 141 suspension, the Dual Shock SR 146 offers increased flotation and comfort thanks to its longer length and comfort tuned torsion springs and high pressure gas shocks at both front and rear arms. The lightweight suspension serves up excellent flotation off-trail but is primarily designed for on-trail duties with superior traction for improved acceleration and braking performance along with impressive bump absorption across a wide range of trail conditions, from freshly groomed to trail chatter to larger bumps and unpredictable terrain.
Auxiliary Rear Fuel Tank/Storage
A rear-mounted fuel tank with a capacity of 16.3L dramatically extends range for those who crave long distance riding without stopping. The system is designed to use fuel from the auxiliary tank first, thereby keeping the vehicle balanced. In addition, a rear mounted storage area adjacent to the tank offers extensive space for additional gear and features a quick latch cover to keep gear out of the elements while blending seamlessly with the overall lines of the snowmobile.
Tapered tunnel design
The SRViper S-TX 146 DX'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 146 DX's generous 37-litre fuel tank combines with the Genesis engine's acknowledged fuel efficiency to keep you on the trail longer. The Viper S-TX'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 146 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.
The SRViper S-TX 146 DX comes with a heated seat to help keep you comfortable even in the coldest temperatures. The high-low-off control switch is located on the cab of the sled.
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.
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 SRViper S-TX 146 DX 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.
