2018 Yamaha Sidewinder X-TX SE 141, 2018 Yamaha Sidewinder X-TX SE 141 YOU CHOOSE WHERE TO RIDE. The best-selling chassis configuration is paired with the strongest engine we're ever made in a sled -- Genesis Turbo! Features may include: 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 X-TX SE 141 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 141 Rear Suspension The unique Dual Shock SR 141 rear suspension is a 'torsion springless' design incorporating an infinitely adjustable FOX® FLOAT® 3 air-shock at the rear arm for reduced weight and limitless tuning capabilities. The open and clean look of the suspension allows snow to evacuate quickly and easily, eliminating build up and unwanted weight. In addition, the uncoupled design delivers excellent flotation and conforms to terrain in an effort to deliver optimum traction in a wide variety of conditions. The performance-tuned design sacrifices little on trail as well, thanks to its bump bridging capabilities and impressive acceleration and braking attributes. 1.6-inch Cobra Track Blending the best of on-trail bite and off-trail flotation and traction, the 1.6- inch lug Cobra track is a key contributor to Sidewinder X-TX SE 141 versatile make-up. The 141 length combined with the unique Cobra lug pattern give the Sidewinder X-TX SE 141 a good balance between cornering grip and straight line acceleration. 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.
