Jonathan Rea underlined his superiority on the second day of the final 2015 World Superbike test by dipping beneath this year's pole winning time at Jerez.

Continuing to get better acquainted with the new ZX-10R, Rea stopped the clock at 1min 40.139secs, proving a tenth quicker than Tom Sykes' pole-winning lap time from the Jerez WSBK event in September despite chilly conditions.

Furthermore, it would see the Ulsterman - who took 14 wins on the way to a dominant 2015 World Superbike title - prove a full four tenths faster than team-mate Sykes on the end-of-day timesheets as Kawasaki's latest machine continues to make impressive progress.
