In 1978, Honda Motor Co., Ltd.’s motor sports service division “RSC / Racing Service Center.Co”
released the road racer “Honda RS250R” equipped with an air-cooled 2-cycle single-cylinder engine of the off-road machine “Elsinore” .
The GP250 Road Racer was developed after a long period of inactivity in the Grand Prix race since 1967.
However, it seems that it was not yet a machine that could compete with “Kawasaki KR250” and “Yamaha TZ250” on an equal footing.
