Ducati rider Chaz Davies and Kawasaki's Tom Sykes have completed a two-day test at Aragon in preparation for the 2016 World Superbike season.
Davies, who finished runner-up to Jonathan Rea this past season, tested the updated Ducati Panigale R, while third-placed Sykes rode the new version of the Kawasaki ZX-10R.
"We worked a lot with the new electronics and particularly with the engine brake that is very important to me," said Davies, the lone Ducati rider in attendance as Davide Giugliano continues his recovery from his Laguna Seca crash in July.
"The updates introduced for 2016 are positive and in the end the bike seems to be very stable and consistent, especially at the front."
"We also made an interesting comparison between the racing setting used here in April, that from the end of the season and, lastly, the 2016 version.
"The positive trend has been confirmed, both in terms of feeling with the bike and lap times, an important aspect that confirms we’re moving in the right direction and that gives us confidence for the new season."
New bike "excites" Sykes
Sykes, who finished third in the 2015 standings behind Davies, said: "We worked in a good direction and, generally speaking, we have made a good step forward in terms of feeling compared to the one I had with the 2015 model.
"We ironed out some teething problems and got a general feel for things on the opening days and then today, when the sun was out from start to finish, we got our heads down and worked through a whole book of tricks.
"The overall performance of the Ninja ZX-10R at these tests is something that excites me.
"Overall the lap times were really consistent, and the feeling was easier to achieve than I have been used to. It is still early days but this has definitely been a good start to our winter test programme.”
Reigning champion Rea missed the test as his wife gave birth to his second son, Tyler Jon, but will get to sample the 2016 ZX-10R for the first time next week as testing resumes at Jerez on Tuesday.
