2017 Yamaha SIDEWINDER S-TX 137 DX
- NEW 998cc Genesis Turbo Engine
The new Genesis 998 Turbo 3-cylinder engine delivers 800-class dominating performance in a compact package. The high tech engine system carries a full suite of features to ensure you have a great day on the snow and a fun night when you reach your destination. We use our advanced nine-sensor engine management system to control fuel flow for maximum performance, but it also incorporates a knock sensor to adjust ignition timing and even manifold pressure if the need should arise.
- HIGH TECH TURBO
The Nickel alloy turbine body is extremely strong and precise, able to withstand highly elevated temperatures. Supported by premium, ceramic ball bearings, the Inconel turbine blade assembly is very light and strong. This yields a low moment of inertia for lightning quick response to exhaust gas input.
- NEW YSRC Clutching
Yamaha has well over a decade of experience in harnessing the unique power delivery of a high performance four stroke engine. For the hyper performance Sidewinder S-TX 137 DX, we have developed a new YSRC roller secondary system to deliver aggressive upshifting while also backshifting quickly to keep you in the power. In addition, we slightly upsized the new secondary to overshift and let the Sidewinder X-TX 137 DX stretch its legs on a long lake run.
- Modular Rear Bumper
The integrated eight pocket design of the new wrap-around bumper easily accommodates and wide assortment of accessories and securely holds a host of genuine Yamaha accessories including a two-up seat, rack, or luggage.
- Semi-Rigid Saddlebags
Semi-Ridge Saddlebags come standard and offer extensive storage solutions with weatherproof, easy access zippers. The bags feature a semi-rigid design giving them a sleek and integrated looks that blends flawlessly with the snowmobile.
- Heated Trail Seat
A standard 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 allowing you to explore what lies beyond that next curve from sun-up to sundown in complete comfort.
- Dual Shock SR 137 Rear Suspension
The drop-link style Dual Shock SR 137 rear suspension is the cumulative result of years of punishment and development in snocross and cross-country competition. This “crossover” suspension offers premium bump compliance and control on trail, additional bump bridging capabilities thanks to its stretched length, and additional flotation and traction for occasional off-trail use. The SR 137 is a “coupled” suspension that utilizes a unique “sliding” front arm mount. With up to half-inch of movement at the front arm “slot”, the system allows the SR 137 to deliver controlled (reduced) ski-lift during acceleration while still retaining front arm bump compliance.
