1931 Harley Davidson Model DL. 750cc V-TwinA stunning 1931 Harley Davidson Model DL restored in the late 1990s to mint condition. Since then the Harley has formed part of a small collection of motorcycles that were all exercised regularly but never ridden extensively. The HD has stayed with the same owner for 25 plus years. In fact, prior to restoration in the late 1990s, the HD was passed from father to son, so it belonged to the same family for much longer. The HD remains in superb condition
