2023 Yamaha Sidewinder SRX LE EPS

The Sidewinder SRX has carved a niche in snowmobiling reserved for only the fastest, hardest accelerating production sleds. Its low profile, lean chassis is suspended by a specialized, electronically controlled iQS system that allows you to adjust the ride on-the-fly. New for '23 is the addition of EPS for added handling precision, with lightweight steering character. The combination of iQs and EPS yields a one-two punch for a ride that is unrivalled in the high-performance category. SRX is the 'top-gun' choice of riders looking for maximum velocity when it's a race to the horizon.

Features may include:

• The Sidewinder's lightweight, two-piece, tapered tunnel gives you strength for the long haul and a tapered fit for enhanced leg comfort and overall ride positioning. The reinforced running boards are punched with aggressive boot-hold serrations and offers excellent snow evacuation to keep your feet planted where you want them.

• A standard heated seat provides the ultimate in warmth and comfort on even the coldest winter days. A simple flip of the dash-mounted switch enables the choice of two warmth settings, allowing you to explore what lies beyond that next curve from sun-up to sundown in complete comfort.

• 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 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.

• 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.

• 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 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.
