KEY FEATURES

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 industry’s highest achiever. This engine produces the potent venom in the Sidewinder’s bite.

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 Yamaha designed single keel ski strikes the elusive balance between lightweight steering effort and precision handling over a wide range of snow conditions.

Unique, staggered carbides further enhance steering response.

A special 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.

Handling

The straight steering post on the Sidewinder is configured over the engine. It connects to a single bell crank for simplicity and lightweight. The design also minimizes free-play in the steering system and delivers a tight turning radius.

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.

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.

Performance

Yamaha engineers 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. It’s an innovation not seen in any other production turbo on the planet, and another first for Yamaha with the Genesis turbo.

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.

A dual-piston brake caliper applies braking forces directly to the drive shaft and is mated to a wave-style, lightweight drilled rotor. The LE-only rotor removes one pound of rotating mass from the vehicle’s 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.

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.

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, resulting in ready acceleration and seamless power delivery.

The Yamaha-developed Mitsubishi ECU uses a series of nine 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.

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 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 industry’s highest achiever. This engine is virtually the potent venom of the Sidewinder’s bite.

The ARCS front suspension features taller, high-strength, forged alloy spindles and redesigned lightweight upper A-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.

The Dual Shock SR rear suspension is the cumulative result of years of punishment and development in snocross and cross-country competition. This lightweight suspension offers premium bump compliance with excellent resistance to bottoming. The Dual Shock SR is a ‘coupled’ skid-frame that utilizes a unique sliding front arm mount with half an inch of movement at the front arm slot. This active arm design delivers controlled (reduced) ski-lift during acceleration while retaining a good measure of independent front arm tracking. A solid rear axle layout with a special idler wheel design and configuration provides great durability.
