In a chat with media afterwards, Davies said that after winning race one the small tweaks that the technical team made to the bike helped him to win race two as well.
"I'm really, really happy with these results, and we've definitely seen the fruits of our labour here.
"The track here perhaps limits our weak points and plays to our strengths, and we were able to put together two really good races that went almost exactly to plan.
"I didn't think we'd be able to lap in 1.23s but I was able to make some really quick first laps in Race 1, pushing hard for the first twelve or so and then it was all about gap management," said Davies.
"We made a few small tweaks for race 2 and I think those changes were useful. I took a lot of risks with the rain, and was very worried about crashing but luckily the rain stopped and things went smoothly from there to the finish line.
"I thank my entire team, Ducati and our sponsors – it's been a really solid weekend and a lot better than last year's outcome of course," he added.
The next round of the WSBK Championship takes place on August 2 at Sepang, Malaysia.
