Fuel-injected 1049cc 3-cylinder engine

One of the most respected engines in the snowmobile world, this smooth 3-cylinder unit is a joy to use at any altitude - in any conditions. An economical 4-stroke with our very latest re-calibrated fuel injection system, it delivers excellent cold-start performance, instant throttle response and huge pulling power across the rev band.

Agile, responsive chassis - low weight with high strength

The super-tough chassis, specially engineered for our latest Mountain models, features aluminium construction with a high load-bearing, triangulated design to keep weight low and strength high. The result is razor-sharp agility and a superbly balanced ride, with dynamics to complement a wide variety of riding styles.

A comfortable way to celebrate 50 Years!

The striking colour scheme of our 50th Anniversary Edition is a real eye-catcher, but perhaps even more impressive are the luxurious heated Mountain seat, Mountain bars with strap, thumb warmers - and vertical steering spindle. They all combine to give you comfortable control over the gutsy power train and the dynamic, agile chassis.

Asymetric front suspension and narrow ski stance

An outstanding characteristic of all our latest models is the unique design of the suspension and ski geometry. For the front of the B-TX 153 LE we've chosen FOX® Zero/QS3 shocks to deliver ultra-responsive handling - yet with the strength to cope with the demands of this machine's natural deep snow and back country habitat.

Dual Shock SR 153 rear suspension for stablility and control

The SR Viper B-TX offers a range of adjustment and tuning options at the rear, with its FOX® Zero/QS3 shocks package. What's more, the special springless suspension developed for these models greatly reduces the amount (and weight) of built-up snow under the machine, to give you better stability and control.

High-performance Camoplast® Backcountry track

A stunning performer in extreme conditions, the Camoplast® Backcountry track, specially chosen for this SR Viper, features 1.75"/44mm lugs. The track is driven by extrovert drive sprockets which mesh precisely with holes in the track, acting like a gear mechanism to deliver outstanding levels of grip and propulsion.
