It's no secret that turbo charging negates the loss of horsepower at altitude. LARGE FUEL TANK: The generous 10-gal (38 l) fuel tank of the Sidewinder M-TX LE 162 serves more purposes than just carrying a day's worth of fuel. It also cradles the battery and is the platform for the quick-release mountain seat. 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.
