Isle of Man TT technical chief Adrian Gorst has apologised for a ‘heat of the moment’ comment he made regarding the eligibility of Ian Hutchinson’s Supersport pistons which prompted the Bingley rider to speak out during the Senior post-race press conference.

“I made an initial comment in the heat of the moment during post race inspection but on closer examination and after reviewing the TT regulations it became clear that the piston was eligible and complied with the Technical Regulations for the Supersport Class,” said Gorst.

“At no point were any of the machines formally declared illegal and no formal protest was received from any of the other competing teams or riders. I would like to apologise to anyone affected by my comment.”
