After Peter Hickman notched up a 132mph lap on his FHO Racing BMW Superbike on Tuesday evening, Harrison raised the game for practice week in 2023 on Wednesday.
Wednesday’s running began with the Superbike and Superstock class session, with Hickman leading the pack away on his Superstock machine for two laps.
Harrison set off behind him on his DAO Racing Kawasaki Superbike, and set the initial pace from a standing start of 133.284mph for the first sub-17-minute lap of TT 2023 at 16m59.089s.
Hickman let Harrison through as they thundered along the start/finish straight on the Glencrutchery Road, with the Kawasaki rider released to put in a stunning final flying lap on his Superbike.
Harrison completed the lap at 133.514mph, which would keep him top overall as the evening’s running continued.
Michael Dunlop was second-quickest on his Hawk Racing Honda with a 133.367mph, set on his second lap on his Superbike having started on his Superstock Honda.
Hickman completed the top three having only gotten one lap in on his Superbike at 131.862mph, with Jamie Coward (KTS Racing) fourth and John McGuinness fifth – the TT legend setting his first 130mph lap since 2016 on his Honda at 130.035mph.
