It’s based on the company’s 1929-only Model 30A, using the JAP OHV super sports engine that produced 11 HP, with a total-loss oiling system and a single-port cylinder head. The head in this case is a J-series item with enclosed rocker arms and pushrods, which helped keep the dirt out of the machinery and keep the oil (or grease) inside the motor. This Model 30A was clearly stripped-down for racing in the dirt, probably on the increasingly popular dirt tracks of the era for which the factory would, in 1931, make special engines and a shorter chassis based on the successful Speedway pattern of the Rudge frame.
The Model 30A featured an open frame with two top tubes, which the factory abandoned in 1927 but quickly reinstated as the steering head was too weakly supported without that second strut. The engine acts as a stressed member of the chassis, and Husqvarna used the stiff but accurate-steering Druid-type forks with side springs, and in this case, no front brake, as none was required for dirt-oval racing. The leather “bum pad” and special Andre steering damper, plus the abbreviated fenders and open pipe, all speak to the racing history of this machine, which would likely have been modified by a private owner. It uses a 3-speed, hand-shift Sturmey-Archer gearbox and a separate oil tank for the engine oil.
This 1929 Husqvarna Model 30A is a bare-bones but charming 250cc racer from the MC Collection and a perfect example of how private owners modified their own machinery to participate in racing before the factory offered a production racer themselves. It would take another two years for the Model 350DT dirt-track racer to appear, but in the meantime, this terrific little machine was the business. The MC Collection purchased this racer from Sture Haldin in Hallsberg, Sweden, in 2007. He had owned the machine for 25 years, last racing it in 1999. It has a 1929 Husqvarna frame from the Model 30 and a motor from a 1930 machine, and it was restored in the 1980s by Ake Fagerström, a well-known Swedish racer.
