Chaz Davies has hailed his debut double World Superbike Championship victory at Motorland Aragon as beyond his expectations after reeling off a series of personal landmark achievement in one remarkable weekend.

His second event as a BMW GoldBet Motorrad rider, Davies was on superb form from the opening practice session around the Spanish venue - scene of his maiden WSBK podium in 2012 -, before going on to record his maiden front row start in Superpole.

Often regarded as a stronger racer than qualifier, Davies duly made the most of his privileged position at the head of the grid to assert himself as a contender early in race one, only for Eugene Laverty and Tom Sykes ahead of him to retire with mechanical problems. With Sylvain Guintoli posing little threat behind him, Davies was untroubled on the way to securing victory, at that time the second of his burgeoning career.

Keen to complement his success with another good result in race two, Davies proceeded to benefit again from Laverty and Sykes having issues ahead of him to assume the lead on the second lap. It was an advantage he wouldn't cede to the chequered flag, the Welshman winning by more than five seconds.

Completing a fairly dominant double victory, one that catapults him up to second in the overall standings, though Davies says he was hoping to secure a win for BMW in 2013, he wasn't expecting to record two on the same day so early in the season.

"For me it is just an amazing day. I cannot explain how happy I am. What a weekend! My first victory with BMW and then the double win - this is something I was hoping to achieve this year but I did not expect it to happen this early.

"I want to thank BMW and everybody who supported me. I knew coming here that we are going to be strong. BMW has done a fantastic job over the last month we had off since Australia, and everybody was working very hard. In addition, I now really feel that the RR is mine, I feel so comfortable on it.

"In race one, the DNFs by Tom and Eugene definitely made it easier. In race two it seemed that I had a comfortable lead, but to be honest I had to push a lot. One of the most impressing things is the fact that we have done a lot of testing in Jerez but not here in Arag?n, where nearly everybody else has been.

"So to win with that up against us, is quite impressive and it is credit to the work BMW has done. We will now keep being focused, continue to work hard and look forward to Assen, another race track I really like."

In addition to his maiden front row start and double win, Davies also picked up his first-ever fastest lap accolade on the way to victory in race two. It is also the first wins for BMW since it switched its factory backing to the Italian-based, GoldBet-backed Feel Racing team.
