Karl Harris, 34, a three-time British Supersport Champion, was killed during the Superstock Race at the event on 3rd June.
He crashed in an area known as Joey’s Corner during his final lap of the 37.5 mile Mountain Circuit.
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.”
He was the second rider to die in two days, following the death of Bob Price, 65, in Monday’s Supersport race.
It is the sixth death at the Isle of Man TT races since 2011.
Mr Harris won three British Supersport Championshipss between 2001 and 2004 after first appearing on the racing scene as a teenager in the 1990s.
He also raced for Team Great Britain in the Superteen Championship. From there, he went on to win the 1999 European Superstock 1000cc Championship before spending a season in the World Supersport Championship.
Mr Harris made his debut at the Isle of Man event in 2012, finishing 21st in the Superbike race and 28th in the Superstock race.
Guardian photographer, Jason Price, followed the career of Mr Harris for around five years and he had fond memories of the champion.
“He died doing what he loved, he loved the sport,“ Price said.
“It was a massive shock when I found out but that is the danger of the sport.”
“He was a typical Yorkshireman, happy to speak to you and give you his time.”
An investigation has been launched into the circumstances of the accident and the Coroner of Inquests has been informed.
A spokesman for organisers Auto Cycle Union, said: “The ACU wishes to pass on their deepest sympathy to Karl’s family and friends.”
