Lengthy story quick; this motorbike went from Milwaukee to Australia, then again to Iowa, but it’s had simply three house owners in over 100 years!

Noting the “A” in its serial quantity, the bike is a army mannequin that shipped to Australia to assist Allied troops’ efforts there in World Conflict I. After the Conflict, it was bought as surplus, and an Australian man purchased it. He rode it a bit and parked it in his again yard for years, after which it fell over. After seeing the bike on its aspect for a very long time, a neighbor requested about it, provided to choose it up. That man wound up shopping for it and restoring it, repainting it this inexperienced. Although the tank that was laying in opposition to the bottom rusted by way of, all the opposite elements are unique. The present proprietor acquired it from the man who restored it about 20 years in the past, because it sits. He says he was advised the inexperienced was right for typical civilian Mannequin J’s shipped to Australia, although his bike was olive drab when manufactured for the army.

The Mannequin J Harley-Davidson was initially produced for army service round 1915. After World Conflict I Harley-Davidson transformed their manufacturing to serve typical civilian clients. The Mannequin J turned Harley’s prime of the road mannequin. Initially produced in Olive Drab for the army, Harley-Davidson reworked the machine primarily by altering the paint coloration, providing a now acquainted shiny olive inexperienced coloration with delicate striping they used till 1932.

As huge engineering steps had been made, pushed considerably by conflict time expertise developments, with battery ignition changing into the norm, and electrical lights normal together with a 3-speed transmission, the Mannequin J got here into being. It was provided in numerous 61 and 74 cubic inch (1921) variations and served riders effectively till the arrival of the “flathead” Mannequin D round 1929. The J was notable in that in about 15 years of manufacture it had been confirmed on streets, race tracks and even served couriers in World Conflict I. However response to army wants had induced excessive ups and downs in manufacturing: Harley-Davidson manufacturing is famous at a report 27,000 machines in 1920, however with army surplus obtainable it dropped to 11,460 for 1921!

With annual engineering enhancements the J was an excellent higher wager than its predecessors for sidecar use. The body and fork had been stronger and extra pulling energy was obtainable from the J engine which was finally as much as 18 horsepower, up over 50% from its early variations.

This machine is one in all a number of Mannequin J’s and Mannequin JD’s within the Nationwide Motorbike Museum together with the machine on which John Parham sponsored Matt Olsen for the 2012 Cannonball Endurance Run. And several other J engines are mounted on the “Motor Wall” so that you can research.
