Kevin Keyes held on to take his first Pirelli National Superstock 600 victory today after early race leader Korie McGreevey crashed out.

The Century Racing rider led 12 of the shortened 15 laps before binning his comfortable lead, but it was a bad start-line smash that delayed action to begin with before G&S Racing's Keyes eventually took the win.

At least three bikes were involved in a crash off the original start as Team 109's Eunan McGlinchey appeared to stall on the grid.

Connor Wheeler was carted off to the medical centre as technical staff cleaned up the incident, and the race was cut by a few laps for a quick restart.

McGreevey got the best launch when action got back underway as he led Clifford and Motostar graduate Moreton across the line, but the pole-sitter began to break away from the pack and stretch a small gap with Clifford in tow.

And while 2018 Knockhill race winner McGreevey extended a lead of over a second, the podium fight was on as Clifford, Fraser and Keyes began to bunch up.

But disaster struck on lap 12 for the Century Racing rider as he threw away a 1.5s lead after crashing out, leaving Clifford, Fraser and Keyes to move up into contention for the win.

Keyes grabbed the lead coming over the start-finish line to begin the final lap, but Clifford was right on his tail as they jostled for position.

But Keyes made a perfectly timed block heading into Brooklands for the final time to hold off Clifford and Fraser, clinching his first win.
