Kuhn were motorcycles produced from 1968 to 1972 by Gus Kuhn of Stockwell, London.
Prior to 1968, Gus Kuhn had raced at Brooklands and on cinders, and had been more involved with cars than motorcycles. In that year the emphasis shifted when the firm began to produce customized Norton models. They used the Commando for production machine events and a pair of Seeley singles for the open race classes.
Following on came the Gus Kuhn Norton, a cafe racer, available from the custom list, in a variety of specifications. Later they moved away from Norton and onto BMW flat twins.
