In a sport like Moto X, enthusiasm is key. It takes enthusiasm to emerge from a tiny Australian outpost like Baxter, Victoria (population: 1,873) and win several State and National Supercross titles. It takes enthusiasm to make the switch from Supercross to Freestyle on a whim, especially when you should be home nursing your broken leg. Enthusiasm can make you do crazy things, like mocking up fake credentials and sneaking backstage during the Crusty Tour to meet your favorite freestylers (“I still have the photos on my laptop,” says Williams. “I look like I’m about 12 years old!”). And when you find yourself competing against and beating those very same freestylers just three years later, enthusiasm deserves a portion of the credit. So does raw, unbelievable talent.
