The MXZx 600RS E-TEC uses the industry leading REV Gen4 platform with its open cockpit design and entrally balanced engine for superior rider ergonomics and handling in rough conditions. The Gen4 layout delivers agility and responsiveness while the Ergo Step side panels and beveled tunnel allow racers the room they need to attack the course – without interference from the chassis. For 2021 the visible changes are with the front shocks as they upgrade to the 46 mm KYB Pro Series that typically have been available only on a limited basis to the Super teams. Integral Base Valves on all shocks add the ability to adjust not only High and Low Speed Compression but also High Speed rebound. Suspension calibration has changed to match the new shocks with the rest of chassis and is based on direct rider feedback to further handling benefits.
The changes from last year all carry forward; rear of chassis with a re-designed tunnel, heat exchanger, bumper and now new taillight that meets SSCC standards. All shocks, including the new fronts, use the Integral Base Valve that was originally developed on the factory shocks.
The 137 rMotion rear suspension features a sturdy rail design, unique racing geometry and a proven holeshot device.
The RAS 3 front suspension features a long spindle that allows high cornering speeds and a unique race sled only power steering system that provides ultra-precise handling with less effort.
The Rotax 600RS E-TEC engine features E-TEC direct injection, that always delivers quick response and perfect calibration no matter the altitude or weather conditions so racers and their crew have less to worry about. New calibrations for 2021 further refine the holeshot and mid-range power. Other features include booster injectors first deployed on the Rotax 850 E-TEC, a short intake tract with double reeds and digital eRAVE.
