The oil slick was left by Adam Norrodin's motorcycle, the result of a clash during the first lap of the race. The bike left a nice slick right at the braking zone for turn 6, causing the big crash. Despite riders being thrown from their motorcycles, all were declared fit to ride once the race was restarted. The total race was shortened to just 16 laps after the full restart, with everyone but Norrordin rejoining the field. With such a big mess, we're just glad no one got seriously hurt.
