Practice week for the 2015 Isle of Man TT races concluded yesterday evening with John McGuinness and Conor Cummins posting the second and seventh-quickest laps respectively around the 37.73-mile Mountain course on their Honda CBR1000RR Fireblade SP machines.

A change of schedule saw the RST Superbike race being moved to Sunday 7 June and, with the alteration, an additional practice session had been scheduled for today. This session has now been cancelled, however, due to high winds around the circuit.

A week of mixed weather conditions saw the first Superbike outing for the Honda Racing duo cancelled completely on Monday due to rain and high winds, but practice began in earnest on Tuesday.

Both Wednesday's and Thursday's sessions took place in near-perfect conditions with most of the riders recording their fast est times on Thursday night. McGuinness posted a 130.030mph lap, which places him second overall, while team-mate Cummins's 128.331mph lap, also on Thursday, gave him the seventh-fastest time.

Ian Hutchinson topped the overall Superbike timesheet ahead of McGuinness and Bruce Anstey. The six-lap RST Superbike race is scheduled for tomorrow at 2pm.
