Tom Sykes has topped the first day of the unofficial World Superbike pre-season test as several teams converged on Jerez to begin preparations for 2016.
Though some teams had conducted some private testing prior to this week's outing as the winter ban came to an end, the Jerez test is first time Kawasaki, Ducati, Honda, Yamaha, MV Agusta and BMW machinery have all been course at once this year.
By the end of play it was 2013 WSBK champion Sykes that would emerge quickest on the new Kawasaki ZX-10R, his effort of 1min 40.882secs coming towards the end of the day and proving enough to unseat Aruba.it Ducati's Chaz Davies from the top spot.
Defending champion Jonathan Rea made it a strong start to the week for Kawasaki in third, while ex-MotoGP rider Nicky Hayden put in a strong effort on the Honda CBR1000RR, the Superbike rookie fourth fastest and just five tenths adrift of the top spot.
Similarly, it was a positive start for the new PATA Crescent Yamaha R1, with Alex Lowes ensuring four manufacturers inside the top five in fifth place, ahead of Davide Giugliano, Michael van der Mark and Xavi Fores, this year stepping up to World Superbikes full-time with Barni Ducati.
Sylvain Guintoli on the second Yamaha and Leon Camier on the MV Agusta rounded out the top ten, ahead of Sylvain Barrier, the Frenchman making his debut with Pedercini Kawasaki.
Meanwhile, British Superbike champions Shaun Muir Racing made its WSBK debut with its Milwaukee BMW, with Josh Brookes lapping 2.5s off the pace but losing time with technical issues.
