Silicone Racing’s Dean Harrison topped the first night of Superbike TT 2019 practice with a 129.53mph lap to lead Conor Cummins and James Hiller around the Mountain Course.
But it was disaster for both Ian Hutchinson and lap record holder Peter Hickman. Honda’s Hutchinson crashed at the very fast 11th milestone but was reported unhurt while the Smiths BMW man had electronic issues with his S1000RR and didn’t post a lap as he was stuck out at Kirk Michael.
Harrison blitzed the Superstock opposition with a 129.34mph and got over some problems with his Superbike ZX-10RR to top the timesheets with his final lap.
Cummins set his lap from a standing start and was on for a quicker time but was black-flagged for smoke on his flier. He came back to the pits to investigate but his Padgett’s crew couldn’t find anything wrong.
Quattro Kawasaki’s Hillier set a 128.07mph with Dunlop a bit further back with a 126.65mph lap from a standing start on his Tyco BMW.
However, Dunlop’s fourth lap was faster than Harrison in three sectors but he slowed right down from Cronk-ny-Mona to finish a potential 130mph lap at 126.43mph.
Michael Rutter stuck the Bathams RC213V in fifth place with a 126.48mph lap while David Johnson put his works Fireblade into seventh place on a 126.19mph behind Jamie Coward in sixth.
Hutchinson set a lap quick enough for eighth place before his crash but he was pushed back by Phil Crowe. Daley Mathison was tenth and Stefano Bonetti in 11th.
Derek McGee was 12th, Davey Todd 13th and John McGuinness set a 123.73mph for 15th place on the Norton behind Brian McCormack.
