2021 Yamaha SIDEWINDER L-TX SE

SIDEWINDER L-TX SE
The Sidewinder L-TX SE has all the trail performance and capabilities found in our LE models but at a lower price point. The ARCS front suspension with Fox® RC adjustable shocks leads the charge with longer, lightweight forged spindles and optimized geometry. A 137" Ripsaw II track wrapped around the free-arm, coupled SRV rear suspension with HPG shocks hooks up the industry's most powerful engine. The race bred chassis holds you forward, at the ready to meet anything the trail throws your way. Appearance is also racy and aggressive with a minimal, - shorty - wind deflector and hot, high impact graphics.

Dual Shock SR Rear Suspension
The SE gets premium Fox Zero RC front shock absorbers with adjustable coil springs and a wide range of damping adjustments. These shocks include Fox FIST ice scraper technology, velocity sensitive damping and high quality hard chrome rods with T6 anodized 1.5 inch bodies. The skid frame front arm gets an aluminum 1.5 HPG gas shock and the rear duties are carried out by a beefier 2.0 aluminum HPG shock for fade-free performance.

ARCS Front Suspension
Lightweight, with a tall and narrow profile, the X-TX mountain seat is both shorter and more tapered towards the front than our standard trail seat. This allows for easier rider transitions from side-to-side, and improved stand-up ergonomics.  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 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.
• 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.

• 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.
• Regarded as the best high-performance terrain track available, the 137 x 1.25-inch lug design of the RipSaw II delivers incredible acceleration, braking control, and handling in a wide variety of conditions.
• 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.
• 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.
