2018 Yamaha Sidewinder S-TX DX 137 CONQUER SNOW If there's a sleeper in the Yamaha line, the Sidewinder S-TX DX 137 might just be it. Don't let the luggage bags and storage case fool you. Under the hood of this beast is the mighty Genesis 998T engine, ready with boost at any given point. Throw in long distance amenities like heated visor outlets, medium size windshields and heated seats for some of the fastest, most comfortable long distance riding machines in the line 998 YAMAHA GENESIS TURBO ENGINE Industry's highest horsepower Designed around a premium turbo unit to produce uncompromised performance and reliability Yamaha engineered for no turbo lag HEATED TRAIL SEAT Provides ultimate warmth Dash-mounted switch Complete comfort DUAL SHOCK SR 137 REAR SUSPENSION Offers premium ride comfort with additional bump bridgin, flotation and traction Coupled suspension that utilizes a unique sluding front arm mount Reduced ski-lift during acceleration Features may include: 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. 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.
