The Sidewinder S-TX GT EPS produces the most power ever offered in a Yamaha two-up machine. It is simply unrivaled in its overall performance, blurring the line between a sporty trail touring package and all-out lake racer. Powered by the mighty Yamaha Genesis 998 turbo, this fully featured flagship cruiser stands above all other passenger-capable snowmobiles. The addition of Yamaha Electric Power Steering (EPS) reduces rider fatigue. Along with its dual tanks providing extended fuel range, storage capacity for two, plus all the comfort and warmth you’d expect from a luxury sled, there is nothing else quite like it on snow.
