Guy Martin is a six-time winner at the Ulster Grand Prix

Guy Martin was fastest in the Superbike class in Thursday's rain-delayed practice for the Ulster GP at Dundrod.

The Relentless TAS Suzuki rider from England went round at 120.17mph, ahead of Cameron Donald and Keith Amor.

Ballymoney's Michael Dunlop (120.86) edged out Martin in the Superstocks while Amor topped the Supersport times from Michael Dunlop and Donald.

Ian Lougher was quickest in the 250s and Ryan Farquhar was second to Wayne Hamilton in the Supertwins.

Farquahar has dominated the Supertwins class but Hamilton's 110.23 easily eclipsed the 108.30 from the Dungannon man.

Lincolnshire rider Martin produces his best on the Dundrod circuit and he will be seeking his seventh Ulster GP win on Saturday.

William Dunlop from Ballymoney was the top local rider in the Superbikes in fifth, with Farquhar sixth and Michael Dunlop seventh.
