When ample snow is combined with an expansive trail network, you require a snowmobile capable of doing it all without compromise. Spring Power Surge Exclusive!
High Tech, Liquid Cooled Turbo
The nickel alloy turbine body is extremely strong and precise, able to withstand highly elevated temperatures. Engine coolant is circulated through the turbocharger to control both underhood 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 component.
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.
Triple Throttle Body Induction
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.
Electronic Air Bypass Valve (ABV)
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.
FOX® ZERO QS3 Shock Package
The front suspension features FOX ZERO QS3 gas shocks with remote reservoir, 3-way damping adjusters and pre-load adjustable coil-over springs. These shocks include Fox FIST ice scrapper technology, velocity sensitive damping and high quality hard chrome rods with T6 anodized 1.5 inch bodies. Both the front skid frame arm and the rear arm are fitted with premium FOX ZERO QS3 damping adjustable, remote reservoir, shock absorbers.
SRV Front Suspension Crossover, 40"
Sidewinder X-TX LE 141 features slim "mountain" spindles and new single keel "cross-over" skis to aid quick, responsive manouevers in deep snow. 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.
Lightweight, Rigid SRV Chassis
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.
Yamaha Mountain Ski
The lightweight Yamaha Mountain Ski delivers everything you want in a deep snow ski. Its wide footprint enhances flotation and actively lifts the sled’s nose up on plane in deep powder. Traction lugs on the top of the ski give you a sure foothold when the situation gets really gnarly. The wide and deep keel design deliver light steering effort yet confident and predictable handling on hard pack and in fresh fluff.
NEW Rear Suspension Rails
The new lightweight rear suspension rails include an additional set of front idler wheels. The idlers are now mounted outboard creating additional clearance for premium, adjustable suspension shocks. A solid axle adds strength for the newly designed rear track wheels.
Dual Shock SR 141 Rear Suspension
The unique Dual Shock SR 141 rear suspension eliminates the bulky torsion springs, incorporating a full complement of FOX® Zero QS3 adjustable, coil-over shock absorbers. The open and clean look of the suspension allows snow to evacuate quickly and easily, eliminating build up and unwanted weight. In addition, the uncoupled design delivers excellent flotation and conforms to terrain in order to deliver optimum traction while maintaining a playful ride character. A new solid rear axle equipped with newly designed rear wheels and forward, outboard mounted idlers ensure greater durability for the long haul.
NEW Stealth Control System
The handle bar controls feature a left hand switch cluster which allows for "on the fly" access to the new multi-step hand and thumb warmer adjusters. Information available on the multi-function gauge can be easily selected with a convenient toggle switch and the push button reverse gear switch is also located in the left hand cluster. The right side of the bar is clean with a new ergonomically shaped throttle lever and simple, stand-alone emergency stop switch. A new Hayes brake cylinder equipped with a composite "shortie" brake lever provides greater modulation for better feel and powerful stopping performance.
NEW Medium Tunnel Bag
Additional storage is provided by a convenient new tunnel bag. Its semi-rigid design makes it easy to access and is water resistant to keep your spares safe and dry.
