Michael Dunlop looked set to post a 130mph lap and go quickest overall towards the end of Tuesday night’s practice session after posting a number of best sector times.
However, he slowed towards the end of the lap and arrived back at parc ferme with his rear wheel locked due to an overheating rear brake - such was the heat, a small fire broke out before it was quickly extinguished.
Peter Hickman pulled off the course twice during Tuesday evening. The first time, on the Smiths Racing BMW S1000RR Superstock bike saw him only get as far as Quarter Bridge before pulling off due to a software issue preventing the bike from revving above 9000rpm.
He went back out for two laps on his Supersport machine, setting the fastest lap of the evening, before taking his Superbike out for the first time. On this occasion, a throttle issue caused him to pull off at Douglas Road Corner.
Conor Cummins, like Dunlop, had a potential 130mph lap taken away from him after he was black flagged at Brandywell. Smoke had been reported to be coming from the Milenco by Padgetts Motorcycles Honda, which was caused by the heat pads rubbing against the exhaust pipe, and he was subsquently allowed to continue.
Gary Johnson also got black flagged on the RAF & Regular Reserve Kawasaki at Douglas Road Corner after the GPS sensor on the back of the bike worked its way loose and was left hanging on only by a wire.
2017 double Manx Grand Prix winner Michael Evans has been ruled out of this year’s TT after sustaining a broken collarbone at the Pre-TT Classic races at Billown. His 600cc Wilcock Consulting Honda has been taken over by Jonathan Perry.
Forest Dunn set his first ever 120mph lap, albeit unofficially, in Tuesday’s session with a lap of 120.074mph.
Swiss rider Lukas Maurer is the fastest newcomer so far this week with a lap of 114.503mph on his Kawasaki Superstock machine while fellow debutante Raymond Casey improved to 112.735mph in the Supersport class on Tuesday.
