Debris on the track meant that a red flag briefly halted proceedings, but the 2019 British Superbike champion kept his composure throughout.
Redding topped FP1, leading Ten Kate Yamaha’s Loriz Baz by over a second, and with conditions improving heading into FP2, the 27-year-old held on to his advantage to finish on top ahead of a Yamaha pair of Toprak Razgatlioglu and Michael van der Mark, who finished second and third, respectively.
Last year’s opener saw the man that Redding has replaced at Ducati, Alvaro Bautista, storm to three wins in the competition’s curtain-raiser. The Spaniard has since moved to Honda and finished in eighth place in FP2.
The opening race kicks off on Saturday afternoon with Ducati targeting their first World Superbike title since 2011, while ex-MotoGP man Redding is aiming to become the first rookie to win the title for over a decade.
