Dan Thompson clinched the British 500cc Youth Championship with a faultless display at Belle Vue on Saturday.
The 16-year-old Leicester star had trailed twin brother Joe by two points in the series prior to the meeting but reeled off five straight victories at the National Speedway Stadium, winning the Final ahead of home youngster Harry McGurk and Kent’s Jake Mulford.
It meant Dan edged out Joe by four points overall, with McGurk claiming third place in the end-of-series rankings.
At 250cc level, Luke Harrison clinched the title as his season-long duel with Max James went right down to a run-off.
Harrison’s win at Belle Vue meant the two riders were level at the end of the series, and in the deciding race he surged inside his opponent on turn three to take the title.
Third place on the night went to Cameron Taylor, with Ashton Vale taking bronze overall.
There was also a close finish in the 125cc class, where Sonny Springer’s win on the night over Ace Pijper and William Cairns saw him move above Max Perry and become Champion.
Cairns was second overall whilst Perry endured an unfortunate night in Manchester and had to be content with third in the series.
Support classes on the night were won by Danny Smith (500cc) and Stene Pijper (125cc).
