    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.

    ARCS front suspension - FOX® 1.5 ZERO IQS shocks

    A special characteristic of this latest model is the unique new Advanced Rolling Center Suspension (ARCS) with its new spindle design and lighter upper A-arms. Which results ultra-reponsive handling with the intelligent, electrically adjustable FOX 1.5 ZERO iQS shocks. A sturdy suspension set up to tackle any trail or track.

    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 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, continuously 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!

    High-performance Camso® BackCountry track

    A powerful performer in all conditions, the Camso® BackCountry track, specially chosen for this Sidewinder, features 1.75"/44mm 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.

    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.

    Dual Shock SR 137 rear suspension

    The Sidewinder L-TX GT offers an impressive range of easily adjustable tuning options, thanks to its intelligent FOX® iQS shock and torsion spring set-up. Soften it up for fresh powder riding - or stiffen it for fast trail blazing. Setting it anywhere in between is fine too - just experiment a little, then match it to your own riding style.
