Yelverton Union was a motorcycle produced by W. G. Battershill probably of Yelverton in Devon.
This machine was a one-off, made by a carpenter who constructed the frame and forks of his motorcycle in wood - three-quarter-inch square-section ash. The members were straight and laid out in a duplex form with girder-style forks, which were controlled by a tension spring and using bicycle hubs as link pivots.
The engine was a 292cc Union two-stroke, with the EIC magneto mounted in-line with the crankshaft on the right and a large flywheel on the left. Transmission was by direct-belt drive and the machine was used by its builder for thirty-five years before being passed on to another owner.
