As the 450 Class field exited the first turn to start Moto 2 it was Musquin emerging with his third Motosport.com Holeshot of 2019, narrowly edging out Osborne and Barcia. In an attempt to get himself to the front quickly, Barcia lost the front end in a high speed sweeping turn, losing valuable positions. At the completion of the opening lap Musquin led the way with Osborne and Roczen in hot pursuit.
With a clear track advantage, Musquin pushed hard to try and distance himself from the riders behind him, however, first moto winner Roczen made the move on Osborne to takeover second and would soon find himself hot on the heels of Musquin. On Lap 3, Roczen grabbed a handful of throttle and launched into the lead. Musquin quickly reacted in an attempt to strike back, but Roczen held on to the top spot.
Similar to the first moto, Roczen’s impressive efforts out front continued as he once again built a commanding lead, taking his fifth moto win of the season by 22.4 seconds over Musquin. A late race charge by Tomac allowed him to make the move on Osborne and take the final step of the podium in third.
