5. Clement – 1902


Regarded as the first ever V-Four-powered competition motorcycle, the Clement racing machine was built to compete on the growing number of board tracks circuits in Europe. The 1200cc engine powering the Clement accelerated the bike to upwards of 70 mph, but was often beaten by lighter, smaller-capacity and better handling competitors. By 1912 the bike’s constructor, Adolphe Clement, had returned to machines of less displacement using an overhead-valve 47cc motor to power a bicycle – quite possibly the world’s first moped.
