The World Superbike Championship has fired back into action with Ducati dominating the opening day of a private test at Jerez.

Ahead of the second WSBK round at Motorland Aragon, five of the teams have travelled out to Spain to bring themselves up to speed and prepare themselves for a busy European period, with Davide Giugliano and Chaz Davies confirming the positive steps forward made by Ducati over the winter by pacing the first day.

Quickest of all was Giugliano by a comfortable four tenths of a second, ahead of 1199 Panigale team-mate Davies, while Tom Sykes followed up in third on the Kawasaki a further tenth behind.

After a difficult opening round, Jonathan Rea - who didn't race at Jerez in 2013 - was fourth best for Pata Honda, ahead of leading Aprilia rider Sylvain Guintoli and Suzuki's Alex Lowes, the WSBK rookie showing good pace despite his injured ankle.

Marco Melandri, Loris Baz, Leon Haslam and Phillip Island race winner Eugene Laverty rounded out the top ten, while Kawasaki Racing's David Salom was 11th quickest as the sole EVO rider present at the test.
