A fantastic restoration opportunity of a rare Veteran

Zenith Motorcycles was a British motorcycle and automobile manufacturer established in Finsbury Park, London in 1903, by W. G Bowers. The manufacture of automobiles only lasted from 1905–1906. The first Zenith motorcycle was the 'Bi-Car' of 1903, based on Tooley's Bi-Car design, which was purchased by Zenith for its own production. Fred ('Freddie') W. Barnes was hired as chief engineer in 1905 and patented the 'Gradua' variable-ratio belt drive transmission that year. The Gradua system simultaneously changed the diameter of the crankshaft belt-drive pulley to alter the drive ratio, while moving the rear wheel forward or back to maintain belt tension. The Gradua system was among the first attempts to provide multiple drive ratios for a motorcycle, at a time when very simple, direct belt-drive transmission was the industry norm.
This 1912 Zenith Gradua 680 V-Twin has just come out of its 25 year storage, and today presents a wonderful opportunity to restore one of the great Veteran machines of the day. It is mostly complete with some small sundry components missing, which you should be able to source from autojumbles etc. The Zenith turns over with compression and is complete with its starting handle. Sold as a project with some 1980s photographs of the machine.
