Calibrated to swallow the meanest bumps and provide arm stretching acceleration. Spring Power Surge Exclusive! Top Features 998 Genesis Turbo Engine: The 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 the pressed forged crank to the cast steel exhaust manifold is dedicated to producing uncompromised performance. The proven Yamaha engine has earned the respect and reputation befitting the industries highest achiever. This engine produces the potent venom in the Sidewinder's bite. YSRC High Performance Clutch System: The YSRC primary and roller secondary clutches are recalibrated with a new helix for durable, cooler 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. FOX® Zero iQS Shock Package: The new FOX Intelligent Quick Shift (iQS) shock absorbers are employed up front and on the rear arm. Suspension can be adjusted on the fly using a left hand mounted switch on the bars. Compression damping is offered in three very noticable steps from soft to firm. Once activated the SCU (suspension control unit), located on the shock body, alters the oil flow within all applicable shocks in less than one second allowing the rider to dial in suspension feel to the running conditions. The shock setting is clearly displayed in the left side digital gauge once the selection is made. Rebound damping is preset, remaining constant to control kick-back and "packing" in the rough, regardless of the iQS compression selection. 137x1.6 Inch Cobra Track: The Sidewinder L-TX LE features the additional bite of a deep lug, snowcross race inspired, Cobra track. To get the most out of the potential acceleration provided by the 1.6 inch lugs, the overall drive ratio has been dropped down using 24/50 gearing. Combined with the FOX® iQS Zero shock package, the Sidewinder L-TX LE devours kicked out, loose terrain. Corner to corner acceleration blurrs with a flick of the thumb.
