Sidewinder B-TX LE 153

Key Features

Features Gallery
  • alt

    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.

    Agile, responsive chassis - low weight with high strength

    The tough Mountain chassis, engineered for the Sidewinder series, features aluminium construction with a load-bearing, triangulated design to help keep weight low and strength high. The result is razor-sharp agility and a superbly balanced ride, with the dynamics to complement a huge variety of riding styles.

    A comfortable riding position tuned to your style

    The comfort of the specially shaped seat, the sturdy J-hook bars with mountain strap, the lightweight steering spindle - all combine to give you not only comfortable control over the dynamic, agile chassis, but as a result, great confidence in handling the machine. Easy counter-steering on steep sidehills comes naturally too.

    Asymetric front suspension and narrow ski stance

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

    Dual Shock rear suspension for stablility and control

    With FOX® QS3 centre and rear shocks, the B-TX offers an impressive range of easily adjustable pressure and tuning options. What's more, the special springless suspension developed for these models greatly reduces the amount (and weight) of built-up snow under the machine, giving you better stability and control.

    High-performance Camso® Power Claw track

    A stunning performer in extreme conditions, the Camso® Power Claw track, specially chosen for this Sidewinder, features 2.25" (57mm) 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.

    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.
