998cc Genesis Turbo 4-stroke engine

The most advanced and powerful engine ever to hit the snowmobile industry, this smooth, flexible 3-cylinder unit breathes easily at any altitude - in any conditions. Massive torque and pulling power are assured across the rev band, with instant throttle response and no 'turbo lag'. A genuine power revolution in the 'real' 180HP class.

Asymetric double wishbone front suspension

A special characteristic of this exciting machine is its unique front suspension geometry, with widely spaced lower and upper A-arms mounted asymetrically to the chassis bulkhead. FOX® QS3 HCR shocks deliver ultra-reponsive handling - yet are strong enough to take plenty of punishment on trails and tracks in the back country.

Dual Shock SR 141 rear suspension

The Sidewinder X-TX LE offers an impressive range of easily adjustable pressure and tuning options, thanks to its dual FOX® QS3/1.5 Zero QS3 shock set-up. What's more, the special springless suspension developed for these models has been designed to reduce the amount (and weight) of built-up snow, to give you ultimate stability and control.

High-performance Camoplast® Powerclaw track

A stunning performer in extreme conditions, the Camoplast® Powerclaw track, specially chosen for this new Sidewinder, features 2.25"/57mm lugs. Driven by extrovert drive sprockets meshing precisely with holes in the track, it acts like a gear mechanism, to deliver outstanding levels of grip and propulsion in all snow conditions.

J-hook handlebar and tall riser

A tall, lightweight aluminum riser sets the handlebar at the right height for maximum control in 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.

Deluxe instrument panel with dual digital displays

Multiple sensors ride on board with you, continously monitoring engine data to provide essential rider information. In addition to speed, rpm, fuel, oil temperature and pressure, a wide range of trip-related data can be selected. Like a clock with hour-meter, 'Distance Travelled' information - and even an altimeter!

Yamaha YSRC clutch system

Our YSRC clutch is designed to cope with the massive torque and high power output of the Yamaha 998cc Genesis® Turbo triple. Shifting is extremely efficient with a fast backshift response to match. The high strength castings, efficient cooling and finely tuned settings combine to ensure excellent V-belt durability and low maintenance.
