From the dealer's page
350 RX: 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 350 motocrosser will thrive in many different track conditions. Clearly in a class of its own! The 2-stroke range of motocross models also have been refined with updates to the following: A piston for the 350 that saves weight as well as reduces friction, resulting in a 1.5 hp gain. Updated final gearing for the 250 to improve starts. Muffler that is stronger than the prior model Dunlop MX 34 tires With more torque, increased horsepower, and a refined chassis setup, the 350 RX doesn't just compete—it defines a standard for what a big-bore two-stroke is capable of achieving.
