Without a doubt, you are the fastest snowmobile on the trails. Bar none. 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.

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. This is something that has not been 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.

• Handling

Sidewinder SRX LE uses a 137 inch long, low, 1" profile two-ply track in a 2.86, fully clipped configuration. The lower lug profile yields less wind resistance at high speed while the fully clipped track reduces friction to provide maximum top speed performance. Additionally the low lug reduces weight and stress on the track for improved durability and performance at sustained high speeds.

The straight steering post on the Sidewinder SRX LE 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.

The SRV front suspension geometry is aimed at managing spindle camber, resulting in minimized bump-steer and maximized cornering bite providing greater 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.

• Comfort

The handle bar controls feature a left hand switch cluster which allows for "on the fly" access to the iQS electronic suspension adjustments along with new multi-step hand and thumb warmer adjusters. Information available on the multi-function gauge can be easily selected with a 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.
