The April digital edition of Racer X Illustrated has been released. In it, we catch up with Travis Pastrana as he embarks on the Nitro Circus Live tour, shadow Monster Energy Kawasaki’s Ryan Villopoto as his 2014 season begins, and examine the numbers behind the first three Monster Energy AMA Supercross rounds. We also follow Brian Sjogren around Anaheim 1 to see what a young racer's first pro supercross is really like. All this and more are in the April issue of Racer X.  The issue has also been shipped to subscribers and is available for purchase via Apple Newsstand.
