High Performance Genesis 4-stroke engine
The over-achieving Genesis® engine is the heart of our lightweight and aggressive SR Viper 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.
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 SR Viper LTX SE 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 SR Viper LTX SE’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 SR Viper LTX SE’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 137 x 1.25-inch Camoplast® Rip Saw™ II track
The SR Viper LTX SE uses the extraordinary Camoplast® Ripsaw II™ track, measuring 15 by 137 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 SR Viper LTX SE 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.
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 SR Viper LTX SE 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 LTX SE 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 SR Viper LTX SE 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.
Plastic trail ski
The SR Viper LTX SE’s plastic trail ski features a single keel design. The deep, stiff keel delivers confident and consistent cornering bite across a wide variety of snow conditions.
Tall, hooked handlebars
To match the SR Viper LTX SE’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.
Performance-tuned Fox FLOAT2 front shock package
The SR Viper LTX SE’s performance-tuned Fox® FLOAT® 2 shocks use an air spring designed to force the piston to rebound. This eliminates the need for heavier steel coil springs. The air springs are individually tunable by using a pocket-sized air pump, which comes with the sled, so consumers will be able to set the front suspension up to their liking.
Dual Shock SR 137 rear suspension
Bred for the trails but inspired by world class racers, the Dual Shock SR 137 rear suspension gives you a supple 13.5-inches of performance-tuned travel. The SR Viper LTX SE’s high pressure gas shocks take your punishment with fade-resistant action over the bumps or when you want to challenge the terrain. With a half-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 wheelset. The ingenious design is lighter, more durable and more rigid than most traditional rear axle wheels.
Tapered tunnel design
The SR Viper LTX 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 SR Viper LTX SE’s generous 10.6-gallon fuel tank combines with the Genesis engine’s acknowledged fuel efficiency to keep you on the trail longer. The Viper LTX SE’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 SR Viper LTX SE is anatomically designed to comfortably put the rider in an aggressive posture with easy transitions from seated to standing to leaning into a corner.
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 SR Viper LTX SE 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.
