Launched at the 1948 British motor show as the quiet, clean motorcycle for everyman, the LE Mk I was a 149 cc water-cooled flat twin with shaft drive, a pressed-steel frame, leg shields and a rubber-mounted engine. It was easy to ride and gentle, though slow, and later became a mainstay of British police forces.
