Michael Dunlop warmed up for Saturday's Ulster Grand Prix by taking victory in a shortened Superbike race at the Dundrod 150 on Thursday evening.

The race had to be red flagged after two laps due to an incident but Dunlop was later declared the winner.

Dunlop was 0.60 seconds ahead of Bruce Anstey with Conor Cummins in third.

Earlier, Dunlop set the fastest times for the Ulster Grand Prix Superbike and Superstock classes in delayed practice sessions at Dundrod.

Mist led to the delays but Dunlop was quickly on the pace with a speed of 121.65mph on his Superstock.

The Ballymoney man then secured pole on the BMW Superbike with 131.783, just faster than Peter Hickman's 131.063.

Neil Kernohan won the Dundrod 150 Lightweight race, with Christian Elkin taking the Ultra-Lightweight honours.

Gary Dunlop, son of the legendary Joey Dunlop, was fourth in the Dundrod 150 ultra-lightweight race

Ballymena rider Kernohan finished ahead of runner-up Davy Morgan, Paul Robinson, Paul Owen and Olie Linsdell.

Elkin repeated his Armoy success of two weeks ago, coming home first on his Moto3 machine, followed by Sam Wilson and Derek McGee on 125cc bikes.

Gary Dunlop, son of the late, legendary Joey, claimed a creditable fourth place on his debut at the event, with female competitor Melissa Kennedy fifth.

Graham Kennedy took the flag in the National race and David Jackson in the Challenge event.

Meanwhile, New Zealander Anstey clocked the fastest time for Saturday's two Supersport races, edging out Yamaha-mounted Hutchinson by 1.7 seconds, with Manxman Cummins third.

The 600cc qualifying session was halted prematurely after an incident at Flow Bog, which resulted in Australian rider David Johnson receiving multiple fractures.

Johnson sustained a fractured vertebrae, broken knee, broken ribs, a broken left shoulder blade and a collapsed lung in the crash.

A seven-race programme is scheduled for Saturday, with roads closing at 09:30 BST.
