Designed with the seasoned, high‑mileage rider in mind.
5. Dual Shock SR 137 Q53 Rear Suspension
The Dual Shock SR 137 rear suspension is the cumulative result of years of punishment and development in snocross and cross-country competition. This long travel suspension offers premium ride comfort with additional bump bridging capabilities, floatation and traction. The ride and comfort is further enhanced with HPG center and adjustable Fox® QS3 rear shock absorbers. The SR 137 is a “coupled” suspension that utilizes a unique “sliding” front arm mount. With up to half-inch of movement at the front arm “slot”, the system allows the SR 137 to deliver controlled (reduced) ski-lift during acceleration while still retaining front arm bump compliance.
6. NEW ARCS Front Suspension
The new Advanced Roll Center Suspension (ARCS) features taller, high strength, forged alloy spindles and redesigned lightweight upper Arms. The geometry is further revised to optimize suspension function while increasing ground clearance. This results in greater bite with less chassis roll for more predictable and consistent handling.
7. Stealth Control System
The handle bar controls feature a left hand switch cluster which allows for 'on the fly' access to the multi-step hand and thumb warmer adjusters. Information available on the multi-function gauge can be easily selected with a convenient toggle switch and the push button
reverse gear switch is also located in the left hand cluster. The right side of the bar is clean with an ergonomically shaped throttle lever and simple, stand-alone emergency stop switch. An updated Hayes Stealth brake cylinder equipped with a new composite 'shorty' brake lever provides great modulation for better feel and powerful stopping performance.
High Tech Turbo
The Nickel alloy turbine body is extremely strong and precise, able to withstand highly elevated temperatures. Supported by premium, ceramic ball bearings, the Inconel turbine blade assembly is very light and strong. This yields a low moment of inertia for lightning quick response to exhaust gas input. Triple throttle bodies are used exclusively to further enhance the quick delivery of compressed air from the impeller to intake valves.
Mitsubishi Electronic Control Unit
The Yamaha-developed Mitsubishi ECU uses a series of 9 sensors to gather running condition data which it computes using a predetermined memory ‘map’. It then adjusts ignition timing, fuel delivery, manifold air-pressure and turbo boost pressure to produce maximum performance under any condition - reliably.
Triple Throttle Body Induction
Yamaha wanted an engine that's exceptionally quick to respond with little or no 'lag' as found in a conventional turbo. One of the ways they achieved their goal was to develop an intake system using three separate throttle bodies positioned very close to the intake valves. Instead of just one feeding long intake tubes — something that is not seen in any other production turbo on the planet. And another first for Yamaha with the Genesis turbo.
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 to prevent surge and help maintain impeller speed, always at the ready for the next acceleration with seamless power delivery.
Liquid Cooled Turbo Body
Engine coolant is circulated through the turbocharger to control both under-hood temperature and help cool the intake charge. Upon engine shut down, the convection energy produced by super-heated coolant at the turbo head 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.
Centralized Mass Design
The SRV chassis layout was engineered with the goal of centralizing mass. Approximately 60% of the sled's weight is tightly centered within the main triangulation. The result is a quick-handling, well balanced sled, that's fun to throw around in a wide variety of
SRV Front Suspension
The SRV front suspension geometry is aimed at managing spindle camber, resulting in minimized bump-steer and maximized cornering bite giving 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.
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.
Tall Wind Deflector
Escape the wind and winter chill with a sculpted, functional windshield. A small lip at the top deflects wind and snow up and over the rider at speed, while flared edges provide added protection and warmth for your hands.
Gen3 Tuner Skis
The latest version of the Yamaha Tuner Ski is lightweight and designed for precise 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.
Dual Accessory Power Outlets
A convenient heated visor DC RCA outlet is accompanied by a DC socket style plug to power up or charge your devices simultaneously.
Heated Trail Seat
A standard heated seat provides the ultimate in warmth and comfort on even the coldest of winter days. A simple flip of the dash-mounted switch allows you to choose from two settings of warmth allowing you to explore what lies beyond that next curve from sun-up to sundown in complete comfort.
Handle Bar Controlled Digital Gauge
Full-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. Changing functions is made easy with the switch controls on the left handle bar. We even included a clock so you can watch the time fly.
Push Button Reverse
Convenient handlebar positioning makes shifting to and from reverse easy with just the push of your thumb. A servo motor shifts the drivetrain into reverse simply and consistently. An audible warning beeper reminds you when you are still in reverse.
Push Button Electric Start
As with all Yamaha 4-stroke powered snowmobiles, there is no need to pull on a string to bring the engine to life. Easy electric starting is achieved through a simple handlebar mounted, glove friendly, pushbutton switch.
20" Tunnel Bag
Additional storage is provided by a convenient new under-seat bag. It's semi-rigid design makes it easy to access and is water resistant to keep your spares safe and dry.
