Monster Energy Supercross – Jacksonville: Practice

The Yamahas of James Stewart and Ryan Sipes are posted on the top of the lap time lists after first practice, but there is one more seeded session before all is said and done. Dean Wilson and Justin Barcia are close behind Sipes in the Lites class, while Ryan Dungey and Trey Canard are nipping at Stewart’s heels in the 450 class.
