Steve from Strathbran Speedshop posted a pic of the Speer Special on Dirty Bobbers so had to check out some facts about this racer. Frank Speer built the Speer Special to compete in AMA class C dirt track racing. Between the late 1930’s and 1947, the Speer Special was piloted by Woodrow Wilson “Woody” Gerish who held an AMA Class C license and raced the bike on dirt tracks throughout the New England area.
It has a 1929 HD DL motor and frame, but several racing modifications have been done to the motorcycle. The front forks are from a 1936 RL model, the carburetor is a Linkert M6, and the engine has been heavily modified with high compression heads and drilled connecting rods for lighter weight. Larger intake nipples have been welded to the cylinders and a JD manifold has been added to accommodate the 1-1/4” carburetor. The original sliding gear transmission was also replaced with a 1933-1937 style constant-mesh “slant-top” gear box.
The Speer Special now at Cyclemo’s Motorcycle Museum in Red Boiling Springs, Tennessee.
