Karl Harris, 34, from Sheffield was killed during the Superstock Race at the Isle of Man TT races today.
Harris, a professional Motorbike racer, made his TT Races debut in 2012. He was a triple British Supersport Champion and British Superbike podium finisher.
He was best known for his British Championship career. He was the dominant force in the British Supersport Championship in the early 2000s before becoming a prominent front-runner in the Superbike class.
The Auto-Cycle Union 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."
"The Coroner of Inquests has been informed and an investigation into the circumstances of the accident is underway."
