The 2019 Lucas Oil Pro Motocross Championship reached the halfway point in the season with a distinct change in momentum. Ken Roczen and Eli Tomac have been the two riders sharing the spotlight in the 450 class, but at Southwick this weekend, there were two others joining the battle. Marvin Musquin and Zach Osborne split the moto wins. The result would be Musquin’s second overall in a row. In the 250 class, it was another win for Adam Cianciarulo, but Dylan Ferrandis might well have been fastest rider of the day. For extended coverage of Southwick click here.
