Chaz Davies led the way on day-one of testing in Aragon as Ducati locked out the three fastest times. 

It was the factory team who led for much of the day, with Scott Redding fastest during the morning session and Michael Ruben-Rinaldi for much of the afternoon.

However, with just under two hours left Davies swooped to the top of the leaderboard and remained there until the end as all three riders were separated by just +0.111s. 

Davies made his debut with the GoEleven Ducati team two weeks ago at the Official WorldSBK pre-season test in Barcelona, but has been shy on track action compared to others due to testing positive for Covid-19 last month. 

Speaking after a very positive day, the Welshman said: "Today we tried a different balance on the bike, and we find an interesting direction, but we just started the work. 

"The feedback was quite positive, we compared the bike to the one I used in the past two years here in Aragon. 

"The best thing about today is that I feel quite comfortable with every tyre, and I felt good on the bike. 

"It's a good step forward compared to the Barcelona test, a couple of weeks ago. I think we have a good plan also for tomorrow and some other areas to start to explore!."

Davies has a brilliant record at Aragon having taken seven wins which is the most at any one circuit for the 34 year-old. 

Track action continues tomorrow for the second and final day of running.
