1959 YDS-1 Asama Spec
(1959 / Racing Machine)
This Clubman Racer was created for the Asama Highlands Race by equipping the YDS-1, Japan’s first full-fledged road-going sport model, with a larger fuel tank and other kit parts for racing. It debuted in August 1959 at the 2nd All Japan Clubman Race held in conjunction with the 3rd Asama Highlands Race and went on to be a top performer at amateur races around Japan. This racing version of the YDS-1 lowered the hurdles to race participation, increasing the number of competitors and contributing to the growth of motorcycling culture in Japan.
