Only sixty-or-so twin-cylinder
Crocker street bikes were ever made. And this design, powered by a one-liter (61
ci) V-twin, was the first American-built motorcycle to feature overhead valves—a
few months ahead of the Harley-Davidson knuckle motor.
Unlike George Brough, Al Crocker
brought in few outside parts for his motorcycles: almost everything was made
in-house, even the carburetors. But unlike Brough, Crocker faced serious
competition—from Harley and Indian—and this hastened the brand’s demise.
