Karl Harris, 34, from Sheffield, was killed during the Superstock Race at the Isle of Man TT races today, after an accident.
Harris, a professional Motorbike racer, made his TT Races debut in 2012. He was a triple British Supersport Champion and British Superbike podium finisher.
Gary Thompson, TT Clerk of the Course, said:
"Karl was one of the great characters in the race paddock. His infectious enthusiasm and sense of humour lit up many race meetings. He was a hugely talented racer and will be sorely missed."
