The 2025 Sidewinder S-TX GT EPS is a favourite of our North American Snowmobile Team. Nicknamed the "super-couch," the S-TX will get you there, quickly, smoothly and in style. With all the amenities, like Fox QS3 adjustable shocks, 15.5-litre auxiliary fuel tank and Yamaha's industry first Electric Power Steering, this sled is what you go for when you want to log miles all weekend and feel nothing on Monday.
