 Taichi Yoshimura and Honda in the 1972 Trans am


After Honda's success during 1971 and 1972 in developing, racing and winning on a 2-stroke motocross bike, see here, Honda of Japan decided to sell a production 2-stroke 125 and 250. Now for the first time, Honda would offer a 2-stroke motorcycle to the public. In 1972 Honda factory rider Taichi Yoshimura on the super light-weight RC125 and RC250M works bikes, delivered wins in the 125 and 250 class in the "All Japan Motocross" national championship.  As 1972 was drawing to a close, the 1972 Trans am series was underway in the US. The US market was the biggest market in the world and growing and the Trans am series was the biggest series in the US at that time. To get exposure for the CR250 that would be released in the spring of 1973, Honda decided to enter the last two Trans am races of the series. The last two events were at Carnegie Cycle Park in Northern California and the finale at Saddleback Park in Southern California. Two 1972 RC250M's were painted in the colors of the soon to be released CR250M Elsinore production bikes and local Southern California riders Jim Wilson and Bruce Baron were hired to compete in the 250 support class in the final two events. Honda also decided to send their number one Japanese rider to compete in the open class Taichi Yoshimura. It was Taichi after-all that was most  responsible for the development of the bikes. Taichi was kind enough to send us a brief recollection of the events and photos from his own personal archive. Our good friend Holly translated Taichi's brief story in English.

1972 was the first year that Honda raced with the 2-strokes. It was a last minute decision by Honda of Japan to enter the final two Trans am  races in the States. We didn't have a 500cc bike so a we bored up the cylinder of my RC250M a few cc's. I don't remember exactly what the displacement was but the minimum we had to be for the open class was 251cc. I was the first rider to compete in the Trans am series on a Honda. The team manager of American Honda at the time was John Blum. I don't remember too much about those races but I remember everybody was talking about Marty Tripes and he later joined the Honda factory team in 1973. My results in the two races were as follows.
