After its two-year absence, Southwick was back on the schedule. The uniquely sandy track was more challenging than most, but the Yamalube Star Racing Yamaha riders excelled on its terrain. The team took both holeshots, and held down four, of the top five, overall finishes. Cooper Webb took his third consecutive overall win, going two-one. Moto one’s winner, Jeremy Martin, took second overall. Alex Martin was fourth and Aaron Plessinger fifth. Mitchell Harrison had one of his best rides this season, in the second moto, and finished tenth. He took twelfth overall.
