2018 Yamaha SIDEWINDER S‑TX DX 137
- 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. In only its second year in production the Yamaha turbo has earned the respect and reputation befitting the industries highest achiever. Truly this is the potent venom of a Sidewinder S-TX DX 137 bite.
- YSRC High Performance Clutch System
The YSRC primary and roller secondary clutches were specifically designed for durable, cool operation. They harness and transfer the massive torque produced by the Genesis Turbo, efficiently to the track while minimizing drive belt wear. The primary shifts out aggressively to use all the power on tap while the roller secondary is quick to back-shift and provides additional ratio through its oversize sheaves to keep accelerating long after the others have signed off.
- Dual Shock SR 137 Rear Suspension
The Dual Shock SR 137 rear suspension is the cumulative result of years of punishment and development in snocross and cross-country competition. This long travel suspension offers premium ride comfort with additional bump bridging capabilities, floatation and traction thanks to its stretched length. 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.
- 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.
- EBRS Engine Braking Control
The effect of 4-stroke 'engine braking' when the throttle valves are closed has a significant impact on Handling and ride character. Yamaha developed a special system which employs the ISC (idle speed control) circuit and ECU map using throttle valve movement and RPM information to reduce negative intake pressure during deceleration.
