Conquer Snow
The growth of crossover models has been fueled by riders looking to ride in many different areas. When Yamaha launched the Sidewinder with the Genesis 998T engine, riders of all stripes instantly fell in love with the sheer amount and quality of the power. Paired with a YSRC high performance clutch and a dual shock rear suspension setup, the Sidewinder X-TX SE 141 is the forerunner in the crossover segment. Groomed trails, tight trees, open fields littered with snow ? you choose.

-
998 Genesis Turbo Engine
- The turbo boosted, one liter triple is unmatched when it comes to delivering incredible power with the refinement and quality you have come to expect from a Yamaha. Designed around a premium turbo unit, every engine component from intake to exhaust, is dedicated to producing uncompromised performance. In only its second year in production the Yamaha turbo has earned the respect and reputation befitting the industries highest achiever. Truly this is the potent venom of a Sidewinders bite.
-
YSRC High Performance Clutch System
- The YSRC primary and roller secondary clutches were specifically designed for durable, cool operation. They harness and transfer the massive torque produced by the Genesis Turbo, efficiently to the track while minimizing drive belt wear. The primary shifts out aggressively to use all the power on tap while the roller secondary is quick to back-shift and provides additional ratio through its oversize sheaves to keep accelerating long after the others have signed off.
-
Dual Shock SR 141 Rear Suspension
- The unique Dual Shock SR 141 rear suspension is a 'torsion springless' design incorporating an infinitely adjustable FOX® FLOAT® 3 air-shock at the rear arm for reduced weight and limitless tuning capabilities. The open and clean look of the suspension allows snow to evacuate quickly and easily, eliminating build up and unwanted weight. In addition, the uncoupled design delivers excellent flotation and conforms to terrain in an effort to deliver optimum traction in a wide variety of conditions. The performance-tuned design sacrifices little on trail as well, thanks to its bump bridging capabilities and impressive acceleration and braking attributes.
-
1.6-inch Cobra Track
- Blending the best of on-trail bite and off-trail flotation and traction, the 1.6- inch lug Cobra? track is a key contributor to X-TX SE versatile make-up. The 141 length combined with the unique Cobra lug pattern give the X-TX a good balance between cornering grip and straight line acceleration.
-
EBRS Engine Braking Control
- The effect of 4-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.

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 (APV)
- 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 underhood 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.

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, well balanced sled, that's fun to throw around in a wide variety of conditions.
-
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.
-
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.
-
FOX® FLOAT® 3 Front Shocks
- Lightweight and infinitely adjustable, Float 3 air shocks provide great handling both on and off-trail. The air pressure can be quickly adjusted trail side using the convenient mini-pump (supplied) to dial in ride characteristics for changing conditions.
