Introduced in 1936, there was no 'standard' Crocker, as every customer, echoing Brough Superior practice, could specify the state of tune and displacment of the engine; the cylinder barrels were cast with extra thick walls, and could be extensively overbored; engines were built from 1000cc, to 1490cc, in the most extreme case. The 'typical' 62cu" Big Twin produced ~55-60hp, which exceeded the current sidevalve Indian and HD models by 50%. So confident was Al Crocker in the superiority of his twins, he offered a money-back guarantee for any Crocker owner who was 'beaten' by a standard HD or Indian, and of course, no such buyback was necessary. Crocker had built the fast production motorcycle in the US, with speeds over 110mph the norm. Harley Davidson introduced their first OHV v-twin - the model EL 'Knucklehead' - 6 months after the Crocker, but was 15mph slower.

|The 1940 'Big Tank' Crocker which sold at the Bonhams Quail Lodge Sale for $302,000|
The Crocker has rightly become a coveted and very expensive machine, deserving of its place on the Olympus of Motorcycles, with the Brough SS100 and Vincent Series A Rapide, the world's first 100mph production motorcycles, all big and impressive V-twins built in small numbers for a small and discerning clientele...
