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!

• Performance

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.

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.

• Handling

The front suspension features FOX ZERO QS3 gas shocks with remote resevoir, 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.

Sidedwinder 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.

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.

• Comfort

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.
