Honda has developed its global motorcycle brand through the racetrack, with Soichiro Honda assembling the world's best engineers together to create motorcycles on the road like the Honda RC116. However, Honda quit the motor race in 1967, leaving it with a world-class development team without doing anything. To date, motocross has been dominated by four stroke-powered engines, and has no official national championship in Japan. Furthermore, Soichiro Honda publicly announced that Honda would never build a 2-stroke motorcycle.
The Japan Motor Association introduced a domestic motocross championship from 1967, where a group of Honda engineers - such as their development partners at Suzuki and Yamaha - developed a heavier 2 stroke lighter engine. Suzuki's development program started in 1965, which in 1970 had produced the Suzuki RH70, which was driven by Joel Robert of Belgium won the first Japan FIM World Motorcross Championship.
In August 1971, Honda's development team took a 2-step prototype for motocross racing to the National Championship Mine, Yamaguchi, where it was recognized as Honda. As a result, Soichiro Honda gave his reluctant support to produce not only competitive motocross racers, but also out of the box versions.

Development
Honda CR250M has a 2 step 29 horsepower engine, and weighs up to 229 pounds (104 kg). Designed by Soichiro Miyakoshi, the prototype production machine began testing in Japan in 1971, and on the California motocross track in 1972. The CR250M was Honda's first two-step production racing bike, Honda's first competition bike trail built from zero instead of adapting a street bike , and motocrosser first production. The chome-moly frame, aluminum bodywork, and plastic fenders contribute to its light weight, even after restyling when initial testing showed the framework is too fragile, potentially bending after less than an hour's drive.
Production
Named CR250M globally, it's subtitle Elsinore in North America, after the offroad race at Lake Elsinore, California, the most famous off-road race of the late 1960s and early 1970s. The popularity of CR250M and its derivatives soared after Gary Jones rode the stock machine to win the 1973 AMA 250 series motocross nationwide.
In 1974 CR250M was followed by a smaller version, the Honda CR125M, and the first US Honda factory that opened in 1979 in Marysville, Ohio built CR250Ms.
