Karl Harris opened up top as the fourth round of the ViSK.com British Superbike Championship got underway at Thruxton.
Returning to the scene of his mammoth accident in 2008, when he was collected by Tom Sykes' rider-less Rizla Suzuki, Harris shrugged off any memories to out pace his closest rival by half a second.
Championship leader Leon Camier was second quickest around the fastest circuit on the BSB calendar, marginally ahead of James Ellison, a first time winner last time out at Donington Park less than a week ago.
Stuart Easton backed Harris up in fourth on the second Hydrex Honda, ahead of Glen Richards and the impressive Michael Rutter, who was a strong sixth quickest on the Worx Crescent Suzuki he is riding for the first time this weekend as the replacement for Sylvain Guintoli.
John Laverty was an encouraging seventh on the Buildbase Kawasaki, although it was a tough session all round for the 'green' machine, Donington Park stars Simon Andrews and Julien Da Costa down in 19th and 20th respectively.
Ian Lowry, top Cup runner Gary Mason and Josh Brookes completed the top ten. The session was also notable for the performances of Martin Jessopp, Alastair Fagan and Peter Hickman, the Cup riders going 11th, 12th and 13th respectively, ahead of Tristan Palmer, Chris Walker, Graeme Gowland, Jason O'Halloran.
