2017 Yamaha SIDEWINDER X-TX 137 LE
- 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 X-TX 137 LE, 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 LE stretch its legs on a long lake run.
- Fox QS3 shocks
The three-stage Fox QS3 high-pressure gas shock features a piggyback chamber to deliver reduced fading, exceptional control, and three easy to adjust compression damping performance settings so you can quickly and easily adjust the ride to conditions and riding preference.
- 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 floatation 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.
- Tuner III Skis
Our Deep Keel Tuner III Skis are engineered specifically for the SRV Chassis and the unique characteristics of the Sidewinder X-TX 137 LE. They deliver reduced ski-pressure and near effortless steering; and the dual keel design delivers an assured “bite” in the corners with reduced darting. The design also allows you to customize the handling and feel of your sled with easy to change carbide runners in a variety of insert lengths for the inner and outer keel.
