Though most street-use motorcycles are now equipped with 4-stroke engines, off-road motorcycles, especially moto-cross racers, still mainly use 2-stroke engines because of their high power and light weight. 2-stroke engines for moto-cross racers require the engine characteristics of high power and excellent throttle response on a wide range of engine speeds. These characteristics immediately require an effective exhaust device to improve output performance at the middle-speed range while maintaining high power at the high-speed range. The latest 2-stroke engines maintain such performance by using an exhaust device, and also by the application of extensively improved basic elements such as the scavenging passage arrangement, exhaust timing and passage shape, etc. This paper briefly summarizes continuous efforts for the improvement of our exhaust-system device from its beginning until the present.
