Lea-Francis motorcycles were produced from 1912 to 1924, in Lower Ford Street, in Coventry.
1912 Lea Francis is perhaps better known as a car manufacturer but in the very early days the firm gained a reputation for the excellence of their bicycles. The prototypes of their motorcycle were produced in time for the 1912 Show. The machine was very well received, and featured all-chain drive in oil baths, multi-plate clutch, quickly detachable rear wheel, 2 speed gearbox with kick-starter, and particularly efficient mud-guarding. used JAP engine.

1912 Having already dabbled with cars since about 1904, the firm turned to motorcycles and introduced one model, in August. It had a 3.25hp JAP V-twin engine with chain-driven Bosch magneto, a two-speed gearbox, plate clutch and fully-enclosed chain final-drive. There were also Druid forks and dummy-rim brakes on both wheels. It was offered as a reliable and comfortable tourer.

1914 It was joined by a prototype combination using a 6-hp V-twin MAG engine, but the project was dropped due to the outbreak of war. Meanwhile, the other model was uprated to 3.5-hp JAP V-twin engine.
1915-1916 The 3.5hp model continued, with a three-speed gearbox.

 According to gracysguide The Lea Francis story was recorded by Ken Hallworth in “OLD BIKE” number 18, summer 1996 (I've never seen this mag so I went on line, I found a mention of it in Austrailia, but as that didn't start untill 2009 I don't think it was that one).
