Tilston were motorcycles produced between 1919 and 1920.
As the maker's main business was in the manufacture and promotion of the Gosport spring fork incororating the MacLean system, is ulikely that more than a few of these lightweights were ever made. The machine had a 245cc Precision two-stroke engine with belt drive and swing-arm rear suspension, controlled by a MacLean spring unit sited under the saddle pan.
