The California-based Crocker only produced 72 V-twin motorbikes and the Big Tank is one of them.

The manufacturing process was halted after the Second World War, which increased the value of its motorbikes – making them rare and expensive.

The bike features aluminum fuel tanks, along with a 3-speed transmission. With countless other features, the 1942 Big Tank was the most advanced motorbike at the time of its production.

It was sold for $385,000 at the EJ Cole Collection sale in 2015 making it the most expensive Crocker bike ever sold.
