Tom Booth-Amos celebrated the final British Supersport race of the year with a win at Brands Hatch, as newly-crowned champ Ben Currie crashed out.
After a faultless start, Currie took control of the race, leading all the way to lap 12 when he crashed, handing the lead to Booth-Amos who was running in a strong second position.
With Booth-Amos ahead, Richard Cooper was running second and looked set for another podium but, just half an hour after claiming the ABK Beer 0% BMW Motorrad F900 R Cup title, he too crashed out.
Luke Jones eventually took second, with Eugene McManus third as TJ Toms picked up fourth place, ahead of Jack Nixon.
Cameron Fraser was the first GP2 rider across the line in eighth place, the recently-crowned champ beating Harvey Claridge by just 0.049secs as Harry Rowlings took third.
