The Crocker brand is legendary as a bespoke motorcycle. The company, founded by Al Crocker, an Indian dealer in Denver. By 1932, Crocker had moved to Los Angeles and started out selling OHV hop-up kits for dirt-track Indians in 1932. A year later, Crocker was building a 500cc speedway motorcycle, which had significant success in California’s Bay Area. Just 31 of the Crocker speedway singles were sold.

By 1935, Crocker had an OHV V-twin motor with a hemi head, slightly undersquare architecture, and a three-speed transmission as part of the frame. A year later, Crocker began selling its V-twin motorcycles.

Rather than offering a showroom floor Crocker, the purchaser selected a displacement (ranging from 62ci to 100ci) and a level of tune. According to Crocker, its 62ci motor put out as much as 60 horsepower, far more than the competition. It was capable of speeds over 110 mph when the Knucklehead Harley-Davidsons were still short of triple digits.

According to Crocker historians, approximately 72 of the V-twins were built between 1936 and the end of production in 1942. Early versions of the motorcycle had a 2.5-gallon cast aluminum fuel tank, with the Big Tank versions appearing in 1938. The Crocker sold at auction had the Big Tank and a 62ci powerplant.
