Jonathan Rea was pleased to go into the winter break with a positive four-day test at Jerez behind him, when he continued to hone the set-up of Kawasaki's new ZX-10R.

Having set positive lap times on Monday and Tuesday, Rea and team-mate Tom Sykes raised the bar further on Thursday and Friday, setting impressive lap times on the final day that were close to a second under the World Superbike pole position record.

The Northern Irishman was just two tenths slower than Sykes while using a qualifying tyre before a fall in the afternoon disrupted his day.

Nevertheless after testing several new set-ups and compared Brembo brakes with the Nissins he had used and like during his time with Honda, Rea was more than content to have completed several race runs.

"All in all I am really happy because we have done lots of race simulations and tests already in November, which for me is unheard of," said Rea. "We used a qualifying tyre today, which was really good.

"It opened my eyes a little bit to where we can improve the set-up of our new bike a bit further. For the rest, pretty much until yesterday, we had finalised the main items to test. So today went back to a front set-up and confirmed some things with that. Everything was going OK and I was making runs on race tyres.

"I'm sure I could improve my lap time today, but I'm really happy with the job. The bike seems to be working already as a good base and I am happy to finish the test healthy and enjoy the break until we resume again in January."
