The rain came down again at round five, which caused the track to be wetter and rougher than usual. However, these conditions suited the former off-road rider, Aaron Plessinger, who easily won the second heat race. Unfortunately, the main did not run as smoothly for Yamalube Star Racing Yamaha riders, Plessinger and Reardon, who were both set back by a start pile-up. Plessinger salvaged as many points as he could and finished sixth. Reardon came from twenty-first, to finish in twelfth.
