Welshman Chaz Davies took a double race win at the Spanish round of the Superbike World Championship at Motorland Aragon.

The BMW rider took his maiden world superbike race victory first time out today and backed that up with another win in race two.

But two second places were enough for Aprilia rider Sylvain Guintoli to take the lead in the championship standings ahead of Davies and the second factory Aprilia of Eugene Laverty.

Guintoli now heads the standings with 85 points, with Davies second on 63 and Laverty third on 45 after failing to score a point in either race in Spain.

Laverty and pole-sitter Tom Sykes (Kawasaki) had both led race one but technical problems early on handed the lead to Davies who led home Guintoli and Marco Melandri (BMW).

Fourth went to Jonathan Rea (Honda) ahead of Loris Baz (Kawasaki), Jules Cluzel (Suzuki), Carlos Checa (Ducati), Michel Fabrizio (Aprilia), Leon Haslam (Honda) and Ayrton Badovini (Ducati).

Laverty, who went into the Aragon races as joint leader with team-mate Guintoli, suffered more problems in race two as Davies again took the win.

Guintoli was second with Sykes third from Davide Giugliano (Aprilia) and Melandri.

Sixth went to Baz with the top ten rounded out by Cluzel, Checa, Haslam and Badovini.
