350 RX

350 RX: All new for 2026, this new model replaces the 300 version for the 2026 season. New engine cases, bore and stroke, as well as a twin-plug head to ignite the special power only a big-bore 2-stroke can provide. The longer crankshaft, combined with the final gearing ratio of 14/47, provides a large amount of torque and overall horsepower that will turn some heads. This new 350 motocrosser will thrive in many different track conditions. Clearly in a class of its own!
