Record holder Alastair Seeley has a 19th North West career win in his sights as he leads from William and Michael Dunlop.

There is another Northern Ireland man in fourth - he's 21-year-old Adam McLean from Tobermore who will be making his Isle of Man TT debut in a few weeks' time.

Roars from the crowd as local favourite and 2012 winner William Dunlop powers into the lead but Alastair Seeley quickly regains the lead. Thrilling racing here.

Race favourite Alastair Seeley is setting the pace on the first lap. The 31-year-old from Carrickfergus has won at least one Supersport race at the North West for the last seven years and he's hoping to improve his record tally of 18 overall wins here.

Ian Hutchinson is right behind the 'Wee Wizard', followed by Martin Jessopp, Bruce Anstey, Lee Johnston, Michael Dunlop, William Dunlop, Dean Harrison and James Cowtron.

After an extra sighting lap, the serious racing starts with the Supersport competitors off for the six-lap opening event of the 2017 North West 200.

The brollies are up as riders prepare on the grid. It is dry on other parts of the 8.9-mile road circuit, so lots of thought going into which tyres to go with. There is to be a 10-minute delay with a dry spell predicted.

Race director Mervyn Whyte says the forecast is better for mid-day onwards.

Order at the top of the Supersport grid: 1) Alastair Seeley; 2) Lee Johnston; 3) Michael Dunlop; 4) Martin Jessopp; 5) Dean Harrison; 6) James Hillier

The grid is being cleared for the first race - the six-lap Supersport. England's Martin Jessopp won this class on Thursday night for his first ever win at the North West 200. And the 31-year-old went on to add victory in the Supertwins for a fantastic double.
