    Yamaha YSRC clutch system

    Our YSRC clutch is designed to cope with the massive torque and huge power output of the Yamaha 998cc Genesis® Turbo triple. Shifting is extremely efficient with a fast backshift response to match. The high strength castings, efficient cooling and finely tuned settings combine to ensure excellent V-belt durability and low maintenance.

    Asymmetric double wishbone front suspension

    A special characteristic of this exciting machine is its unique front suspension geometry, with widely spaced lower and upper A-arms mounted asymmetrically to the chassis bulkhead. The FOX® QS3 shocks deliver ultra-responsive handling - yet are strong enough to take plenty of punishment on trails and tracks in the back country.

    Premium comfort levels for driver and passenger

    Super-comfort is the name of the game here - essential for those longer distance touring adventures. The plush seats have two heating levels and 12V outlets are provided for both driver and passenger to plug in their heated visors or other accessories. The rear seat is removable in seconds for when you want to blast off solo!

    Dual-load 146 rear suspension

    Combining on and off-trail comfort with high-speed handling and performance, this system, with its 3-position adjuster, allows you to set the suspension to personal preference, all controlled with utmost precision by the HP Gas centre coil and rear shocks. For 2-up riding, the overload spring offers comfort and anti-bottoming performance.

    Camso® Cobra 1.6"/41mm lug track with extrovert drive

    A stunning performer in even the most extreme conditions, the Camso® Cobra track, specially chosen for this Sidewinder, takes the riding to another level.

    The clean and functional layout makes this machine logical and simple to drive. All command switches are grouped within easy reach of the left thumb, including the push-to-start button, which functions as a Forward/Reverse control when the engine is running.
