The SportMaxx focuses on the essentials of performance, putting the most horsepower possible into a new, lighterweight, more-athletic 2WD Maxx monster. Power comes from the all-new TRX 2.5 Racing Engine. The transmission is lean and mean with an extremely low rotational mass for superior throttle response and quicker acceleration. Rear wheel drive further improves the horsepower-to-weight ratio for exciting driving action that's always ready to hang it out on the edge. The new WideMaxx suspension system is fully adjustable ranging from maximum off-road suspension travel or low and firm for high-speed racing stability. The SportMaxx is a performance-minded machine for a new breed of serious driving enthusiasts.
