The Knucklehead was a revolutionary motorcycle when it was introduced in the 1930’s. It had a four-speed gearbox, dry slump lubrication, and overhead valve V-Twin when other bikes were mostly flatheads. Basically, this was the bike that made Harley-Davidson. Leno brought the bike in the eighties but it just sat in the corner for three decades. And then some day, Leno decided to get it running.

The bike didn’t run since 1952 but amazingly, all this Knucklehead needed was a little TLC, a little gas and two kicks – and she started right up for the first time after sixty years. All he had to do was flushing the carburettor and the tank, change a coil and the tires. Of course, the foot clutch and the hand shift keep the rider busy all the time but according to the archival footage, people enjoyed these bikes back in the day.
