Hawk recently discussed how difficult achieving a 900 was, calling it the biggest moment of his competitive career.
"I knew it was possible, but I couldn't figure out that last element," Hawk said during an interview at the American Express Success Makers Summit.
"I realised I was falling forward each time and the key I was missing was that I needed to shift my weight mid-spin to my back foot. When I started doing that, it all clicked.
"The reason I chased the 900 for so long was for the sake of progression. The thing I have always loved about skating is how it continues to evolve. It's a continually progressing art form and the 900 is one more milestone in the process."
Khury is clearly a skateboarding prodigy, and a future talent to keep an eye on.
