The International Six Days is well known to most bike enthusiasts. Back in 1950 the Swedes wanted their own enduro, so the first “Motoring Six-Days” event was introduced. This gruelling race lasted throughout 50s and was cherished by riders who wanted success despite the sacrifices. It was also the official racing comeback for the Huskvarna Factory after the war.
Carl Heimdahl was one of the leading technicians at Husqvarna’s R&D department, having been contracted by the factory from the beginning of the 30s. Among his other achievements Carl was also responsible as the chief engineer for the coming ‘Silver Arrow’ – Husqvarna’s biggest street success throughout history. He was also a keen competitor and had collected a lot of trophies on his bookshelf. In the beginning of 1950, the newly developed 125cc engine was ready for testing at the factory. Since the ‘Motoring Six-Days’ was coming up in mid-May, everyone was looking to finish the new machine in time for this decisive race.
