Suzuki Diamond Free

 

 

 

Released in March 1953, the Diamond Free proved hugely popular, with its double-sprocket wheel mechanism for avoiding power loss. With 2-speed transmission and output of a mere 2ps at 4,000rpm, it had a maximum speed of 60km/h. The combined effect of victory in the Mt. Fuji hill climb race and the machine's showing in across-Japan performance testing led to an explosion in demand. The displacement was subsequently increased from 60cc to 70cc.
