Kyrle was a motorcycle produced in 1903 by G. and W. Butcher of Brookend Street, Ross-on-Wye in Herefordshire.
This company claimed to make the engine as well as the cycle parts of the Kyrle. As a cycle business in a rural town, they may have had access to a foundry and machining. They were, however, only short lived.
