Jonathan Rea set the pace for Kawasaki on the first day of World Superbike testing at Jerez, though inclement weather conditions would limit track time for all participants.

Following his maiden run with the manufacturer in Aragon, Rea was up to speed again on the Kawasaki ZX-10R, lapping in 1min 44.643secs on a circuit that only ever reached an optimum condition of being mostly dry with wet patches.

As a reference point, Loris Baz's pole position from the Jerez event in September was a 1min 40.298secs, though several riders didn't run with transponders and didn't provide official lap times.
