2018 Snowmobiles

Let the Viper strike - and escape the trails!

Its biological namesake, the viper, is fast, strong, fearless and perfectly evolved to dominate its territory. In the same way, the Yamaha version rules its own natural habitat – the back country.

At our Viper’s heart is the powerful and responsive Genesis 4-stroke engine, cocooned in a light, strong pyramid chassis. Poise and agility is assured by the asymetric crossover suspension up front – which makes sure the wide flotation Tuner Gen 3 skis go smoothly where they’re pointed – while its phenomenal grip on the snow is down to the rear suspension, with its lean, mean skid wrapped in an aggressive crossover track.

So let the Viper strike now – and enjoy the back country!

Genesis 4-stroke 1049cc High Output engine

While this dynamic powerplant delivers massive bottom-end power, its lightweight crank and recalibrated fuel injection system also deliver thrilling, instant throttle response across the RPM band. Adding to its capability are features like the oil pressure sensing system and the remarkable Engine Braking Reduction System (EBRS).

Asymetric double wishbone front suspension

A special characteristic of this exciting machine is the unique front suspension geometry. The lower and upper A-arms are widely spaced, mounted asymetrically to the chassis bulkhead and matched with aluminium HP Gas and FOX® FLOAT 3 shocks that deliver ultra-reponsive handling - yet are strong enough to take plenty of punishment.

Dual Shock SR 141 rear suspension

No, your eyes will not be deceiving you, the springless rear suspension really is as light as it looks! The rear-mounted FOX® FLOAT 3 shocks eliminate the need for heavy torsion springs. In the centre you'll find we've also thoughtfully fitted an aluminium-body 1.5 HPG High Pressure Gas) shock for maximum control and supreme ride comfort.

Camoplast Cobra® 1.6" lug track with extrovert drive

Acknowledged as the best performer for acceleration and cornering, the Camoplast Cobra® track features 1.6 inch (41 mm) lugs. The track is driven by extrovert drive sprockets. These mesh precisely with holes in the track, acting like a gear mechanism to deliver outstanding levels of grip and propulsion in all conditions.

Wide handlebar and riser

A tall, lightweight aluminum riser sets the handlebar at the right height for maximum control when riding fresh powder. This pivot-adjustable riser allows you to choose the optimum angle for your own riding position. The straight J-hooked handlebar with mountain strap also makes control easier and gives precise feedback from the front suspension.

Dual Digital Meter

Multiple sensors ride on board with you, which continously monitor and measure engine data to provide essential rider information. In addition to the important basics like speed, rpm, fuel, oil temperature and pressure, a range of trip-related data can be selected. Like a clock with hour-meter, 'distance travelled' information - and even an altimeter!

Unique Yamaha YVXC clutch system

The legendary 4-stroke Genesis engine delivers massive power and torque - so needs a tough clutch to match! Ours is engineered to harness that unique, sporty, raring-to-go Genesis character - and optimise your riding experience. A long belt life and the ability to be tuned to altitude - and to your personal preference - are advantages too.
