Robbie Reynard is doing likewise.
Josh Demuth is recovered from his injury that saw him miss most of the season and is returning to action tonight for the Rockstar/H&H Honda team.
Today saw a new qualifying format, as the riders got five minutes on the track, then the practice was red-flagged, the riders were put back at the start, and then the timed practice was started. This is a step in the right direction from before, when everyone was expected to go out on a track they didn't know and put in fast laps right off.
