Genesis Turbo 998cc 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.

A riding position tuned to the mountains

The short, high seat, tapered towards the front, works together with the tall riser handlebar position - with mountain strap - to give you great comfort and control over the agile chassis. Easy counter steering on steep sidehills comes naturally too.

Mountain chassis with lightweight ski spindles

Our latest chassis, first developed for the SRViper Mountain series, features lightweight ski spindles to allow a narrower ski stance without compromising the innovative, high performance design of the suspension geometry. So weight is kept low and strength high. The result is razor-sharp agility and a superbly balanced ride.

Suspension that masters every snow condition

One of the outstanding characteristics of our Sidewinder models is the unique design of their front suspension and ski geometry. This new M-TX LE features independent double wishbone suspension with FOX Float® QS3 shocks and the latest Mountain skis, tuned to deliver ultra-responsive handling - even in the deepest, steepest snow.

Springless 153 rear suspension

There's an impressive range of easily adjustable tuning options, thanks to the FOX FLOAT® shocks - QS3 centres and a QSL rear shock with climb lock-out, which features compression settings of Light, Medium and 'Locked' (1-2-L). In deep snow, the 'L' position prevents rear-arm squat and exaggerated ski lift, for greater control and performance.

Camoplast® Power Claw 3.0"/76mm track

A stunning performer in all conditions, the Camoplast® Power Claw track features 3.0 inch (76 mm) lugs. The 2018 model features a flatter (by 9.7º) track approach angle (thanks to a drive shaft lowered by 28.5mm) resulting in more floatability and manoeuvrability, with outstanding levels of grip and propulsion, particularly in deep snow.

Deluxe instrument panel with dual digital displays

Multiple sensors monitor engine data continuously to provide essential information. Speed, rpm, fuel, oil temperature and pressure and a range of trip-related data can be selected. Like a clock with hour-meter, 'distance travelled' - and even an altimeter! The heated seat and rear storage bag are extra luxuries.

Yamaha YSRC clutch system

The technically advanced YSRC clutch is designed to handle the impressive torque and high power output of the 998cc Yamaha 4-stroke engine. Shifting is extremely efficient with a fast backshift response to match. The high strength castings, efficient cooling and finely tuned settings combine to give excellent V-belt durability and low maintenance.
