This vintage Harley Davidson model F 1918 1000cc V-twin is coming up on it's 100th birthday and it still cranks like new. While some of the frame has suffered decent wear over the past century, the bike itself is in fantastic shape. The original 4-stroke engine cranks out 15 hp, which was more than enough to get this antique down the road even with a sidecar slapped on the side. This three-speed, magneto-equipped Model F was fully restored in 2008 for its 90th birthday and given a new Amal carburettor and electronic ignition to provide a smoother run.
