Riding a motocross bike is no easy thing. These motorcycles are designed to handle very differently compared to a road bike.
Riding them with one hand is something that only a few can master after years of experience and tons of determination.
Craig Parks was one unfortunate rider who met with an accident many years ago and lost his right arm.
Riding an Aprilia RS 250, Parks lost the rear wheel around a left hand corner when he was doing 90 mph. The crash took his arm clean off and he was left with injuries to his legs and hands.
That crash did not stop the biker who had motorcycles infused with his DNA.
With the help of William Craig from "www.prostheticarm.com", Parks was back on a motorcycle, tackling the dirt like a professional.
Parks' motorcycle has been altered a bit to suit his condition because riding motocross is a very physically demanding sport.
Take a look at Craig Parks tackle the dirt yourselves!
