SIDEWINDER SRX LE
The Yamaha Sidewinder SRX LE is ready to defend its title as the world's fastest production snowmobile. With the heart of a Genesis 998 Turbo and specially calibrated iQS, electronically controlled suspension, the SRX is sure to get you to the end of the lake first! A low profile Ripsaw track along with aero tunnel skirts minimize drag while the new, race-bred, ARCS front suspension with longer, forged spindles, special lightweight upper A-arms and new optimized geometry work to keep everything planted. The Limited Edition colour and graphics make for jaw-dropping good looks to accompany that legendary speed, but only for a limited time! |

Fox Zero iQS Shock Package
Fox Intelligent Quick Shift (iQS) shock absorbers are employed up front and on the rear arm. Suspension can be adjusted on the fly using a left hand mounted switch on the bars. Compression damping is offered in three very noticeable steps from soft to firm. Once activated the SCU (suspension control unit), located on the shock body, alters the oil flow within all applicable shocks in less than one second allowing the rider to dial in suspension feel to the running conditions. The shock setting is clearly displayed in the left side digital gauge once the selection is made. There are also two 'driver' select modes which can be preset and held in memory to change the overall settings in one step. Rebound damping is preset, remaining constant to control kick-back and 'packing' in the rough, regardless of the iQS compression selection. |

Stryke' Single Keel Ski
The new Yamaha design, single keel ski, strikes the elusive balance between lightweight steering effort and precision handling over a wide range of snow conditions. Unique, tapered carbides further enhance steering response. A unique shim pad assembly works in conjunction with the rubber saddle block to adjust the carbide pressure point. Overall ski stance is also adjustable by relocating the thick spacer located on each ski axle to the opposite side.ge case and 4 gallon auxiliary fuel tank. Total fuel capacity is bumped up to 11 gallons or 42 liters, which goes a long ways on the trail and your peace of mind.

Low Profile Ripsaw Track
SRX uses a 137 inch long, low, one inch profile multi-ply track in a 2.86, fully clipped configuration. The lower lug profile yields less wind resistance at high speed while the fully clipped track reduces friction to provide maximum top speed performance. Additionally the low lug reduces weight and stress on the track for improved durability and performance at sustained high speeds. |

TOP

- 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. The proven Yamaha turbo has earned the respect and reputation befitting the industries highest achiever. This engine produces the potent venom in the Sidewinders bite.
- The YSRC primary and roller secondary clutches are calibrated 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.

Rebound damping is preset, remaining constant to control kick-back and 'packing' in the rough, regardless of the iQS compression selection.
- The ARCS front suspension features tall, high-strength, forged alloy spindles and lightweight upper A-arms. The geometry is designed to optimize suspension function while increasing ground clearance. This results in greater bite with less chassis roll for more predictable and consistent handling.
- The SRX utilizes special suspension calibration with dual rate front shock springs, and low preload rear torsion springs to provide a lower ride height through additional suspension 'sag'. The lower profile enhances top speed performance while helping keep the sled level in tight corners. The softer initial spring rates are consequently more progressive, ramping up deeper in the stroke to resist harsh bottoming while full travel is still available when unweighted. The SR 137 skid remains 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. The solid rear axle design and large diameter rear wheels provide maximum strength while special front idler wheel layout increases clearance for iQS, plus reduces friction, for greater durability and performance .

Performance
|
- 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.
- 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.
- 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.
- A dual-piston brake caliper applies braking forces directly to the drive shaft and is mated to an wave-style, lightweight drilled rotor. The LE-Only rotor removes 1lb of rotating mass from the vehicles driveline, helping transfer all of the Sidewinder's available horsepower to the snow. The 'Stealth; master cylinder and composite Stealth brake lever offer excellent modulation and feel with ergonomically precise operation.
- 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.
- 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.

Handling
|
- 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.
- 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.
- SRX uses a 137 inch long, low, one inch profile multi-ply track in a 2.86, fully clipped configuration. The lower lug profile yields less wind resistance at high speed while the fully clipped track reduces friction to provide maximum top speed performance. Additionally the low lug reduces weight and stress on the track for improved durability and performance at sustained high speeds.
- The straight steering post on the Sidewinder is configured over the engine. It connects to a single bell crank for simplicity and light weight. The design also minimizes free-play in the steering system and delivers a tight turning radius.
