The June digital edition of Racer X Illustrated has been released. Pick up your copy now to find out how "supercross" became a series in 1974 and why so many of today’s top pros call Daytona their local race. You can also read about the Thailand GP kicking off with a hitch (or five), the incredibly muddy first two rounds of the Grand National Cross Country Series, freeriding in the hills of Beaumont, and more. All these and a lot more are featured in the June issue of Racer X. The issue has also been shipped to subscribers and is available for purchase via Apple Newsstand.
