A twin-cylinder model returned to the Harley-Davidson range for 1911 in redesigned form, boasting mechanically operated inlet valves (replacing the 'atmospheric' type inherited from the single), and production really took off. Known by the sobriquet 'pocket valve', this 'F-head' (inlet-over-exhaust) engine - built in 61ci and 74ci capacities (1,000cc and 1,200cc respectively) - would remain in production for the next 20 years. The Harley single's transmission arrangements - direct drive by means of a leather belt - were continued at first on the twin but the need to make better use of the engine's power characteristics, particularly for sidecar pulling, prompted the introduction of a two-speed rear hub for 1914, by which time chain drive and a proper clutch had been adopted. Later that same year a conventional, three-speed, sliding-gear transmission with 'step starter' was introduced on the top-of-the-range version of the twin which, with full electrical equipment, was listed from now on as the Model JD (and later JE). Periodically revised and up-dated, the Model J had gained a front brake, stronger fork and pumped lubrication by the time production ceased in 1929.

This Model JD was imported (apparently from Australia) in 2002 and comes with C&E Form 386. Its mechanical condition is not known and thus the machine is sold strictly as viewed.
