Frank was a motorcycle produced in 1925 by Messrs. Kerslake's of West Derby, Liverpool.
A design was projected in 1925 that was very futuristic in its suspension system. Powered by a 349cc Bradshaw engine, the prototype was branded Frank and announcements were made in the press that production would commence the following March. Nothing came of the project.
