2020 SIDEWINDER S-TX GT details:



The new Sidewinder S-TX GT produces the most power ever offered in a Yamaha 2-up machine. It absolutely blurs the line between a sporty trail touring package and all out lake-racer. Powered by the mighty Yamaha Genesis 998 turbo, this fully featured flag-ship cruiser stands above all other passenger capable snowmobiles. Extended fuel range, storage capacity for two, plus all the comfort and warmth you'd expect from a luxury sled are a given. Rocket past your buddy's racy big twin with turbo-charged authority.

  • 146 Dual Load Rear Suspension
  • The Dual Shock SR 146 offers a long profile version of our acclaimed trail comfort suspension. This lightweight suspension offers premium bump compliance with excellent resistance to bottoming. The Dual Shock SR 146 is a "coupled" skid-frame that utilizes a unique "sliding" front arm mount with half an inch of movement at the front arm "slot". This active arm design delivers controlled (reduced) ski-lift during acceleration while retaining a good measure of independent front arm tracking. The addition of passenger 'overload' springs help compensate for the extra weight of a passenger to reduce bottoming and maintain balance.
  • Deluxe 2-Piece Heated King Queen Seat
  • A plush 2-up heated seat provides the ultimate in warmth and comfort on even the coldest of winter days. A simple flip of the dash-mounted switch allows you to choose from two settings of warmth and your passenger has their own controls. The passenger also gets a fully adjustable backrest.
  • Tether Switch
  • An integrated switch automatically shuts-down the engine when ever the driver is not on-board.
  • Rear Hard Case with Auxiliary Fuel Tank
  • You wont be caught short on a long ride with the convenient, moisture proof, hard storage case and 15 litre auxiliary fuel tank. Total fuel capacity is bumped up to 49.9 liters, which goes a long ways on the trail (and your peace of mind).
  • 998 Genesis Turbo Engine
  • The turbo boosted, one liter triple is unmatched when it comes to delivering incredible power with the refinement and quality you have come to expect from a Yamaha. Designed around a premium turbo unit, every engine component from intake to exhaust, is dedicated to producing uncompromised performance. The Yamaha turbo has earned the respect and reputation befitting the industry's highest achiever. Truly this is the potent venom of a Sidewinders bite.
