Bingley Bullet Ian Hutchinson almost bagged a stunning 130mph lap during a blistering opening Superbike practice session at the Isle of Man TT.
The 11-time winner made the most of the perfect sunny conditions to clock a time of 129.964mph on his fourth lap on the Tyco BMW, narrowly edging out Northern Ireland's Michael Dunlop for the top spot on Monday night.
Hawk Racing BMW rider Dunlop also completed four laps on his Superbike and posted a lap of 129.670mph from a standing start on his final lap of the night to close the gap on the Yorkshire rider.
However, one of the most impressive feats of the evening came from Bruce Anstey who, after one sighting lap on his Valvoline Racing/Padgetts Honda Fireblade, switched to the hugely anticipated RC213V-S Honda MotoGP replica and recorded a speed of 127.071mph.
Anstey also powered through the speed trap at Sulby at 193.4mph to raise expectations of what is to come from the machine this week.
John McGuinness completed two laps on the Honda Racing Fireblade and went third fastest overall, with the outright lap record-holder clocking 128.871mph
His team-mate, Conor Cummins, was fourth fastest at 127.241mph with the impressive Anstey slotting into fifth on the RCV.
Michael Rutter completed the top six on the Bathams SMT BMW with a lap of 127.031mph.
Ian Lougher was an early retirement on the Suter at Glen Darragh although the Welsh rider later completed a lap of 115.248mph on the two-stroke GP machine.
Bradford's Dean Harrison topped the Superstock class with a speed of 128.044mph, followed by Michael Dunlop on his MD Racing BMW (126.726mph), JG Speedfit Kawasaki's Peter Hickman (125.725mph), McGuinness (125.574mph) and Steve Mercer on the Jackson Honda (124.881mph).
Having had a lengthy session on Saturday evening, not many riders opted to take out their Supersport machines and Harrison was again quickest, as he had been in Saturday's opening session, lapping at 124.461mph followed by Ulsterman Lee Johnston, who clocked 122.067mph on the East Coast/Burdens Triumph.
Karl Foster was reported to have sustained ankle and wrist injuries in an accident at the 32nd Milestone and was taken by airmed to Nobles Hospital in Douglas.
Practice continues on Tuesday evening from 6.20pm.
