BLURRING THE LINES.If backcountry adventures are your thing, the Sidewinder B-TX LE 153 may be just what you're looking for. TAPERED TUNNEL DESIGN: The two-piece, tapered Mountain tunnel of the Sidewinder B-TX LE 153 gives you strength for the long haul and a tapered "fit" for enhanced leg comfort and overall ride positioning. The reinforced running boards are punched with aggressive boot hold serrations and offers excellent snow evacuation to keep your feet planted where you want them. HEATED MOUNTAIN SEAT: Lightweight, with a tall and narrow profile, the Sidewinder B-TX LE 153 mountain seat is both shorter and more tapered towards the front than our standard trail seat. This allows for easier rider transitions from side-to-side, and improved stand-up ergonomics. And you'll appreciate the toasty warm heating element on those cold mornings heading up the mountain. HANDLE BAR CONTROLLED, DIGITAL GAUGE: Full-featured and easy to read, the digital gauge displays critical information in a glance including speed, fuel level, trip mileage, tach, elevation, temperatures and more. Changing functions is now made easy with the switch controls on the left handle bar. We even included a clock so you can watch the time fly. SEMI RIGID SEAT BAG: Additional storage is provided by a convenient new underseat bag. Its semi-rigid design makes it easy to access and is water resistant to keep your gear safe and dry.
