Rea reveals big mistake in Superpole - but happy with second
Rea disappointingly finished in 10th place in qualifying, the worst result of his Kawasaki career, but the 32-year-old managed to recover from the fourth-row start on the grid to claim the runner-up spot in Race 1.
Rea was involved in drama from the start of the race with BMW rider Markus Reiterberger crashing out at the beginning of the first lap after clipping the bike of the reigning champion.
