Karl Harris gave himself the perfect build up to qualifying for the second round of the ViSK.com British Superbike Championship at Oulton Park by topping the third and final free practice session of the weekend.

Completing a trio of best lap times, Harris was on top throughout the 50-minute session, his early attempt of 1min 36.855secs proving good enough to maintain his position in front, with only qualifying now remaining.

His closest rivals, Leon Camier and Stuart Easton, got close with their closing efforts, a hundredth and a tenth behind respectively, although the latter was notable for managing his best on used tyres.

Glen Richards prevented a Hydrex-Airwaves lock out in fourth, the Australian denying James Ellison after the Yamaha rider took a tumble towards the end of the session.

Ian Lowry and Cup rider Gary Mason maintained their impressive form so far this weekend in sixth and seventh, although eighth for championship leader Sylvain Guintoli signified his first appearance inside the top ten on the Worx Crescent Suzuki.

Motorpoint/Henderson Yamaha pair Graeme Gowland and Chris Walker followed in ninth and tenth, but the third Rob Mac prepared machine of Michael Rutter could manage no better than 21st.

Elsewhere, BSB debutant Joshua Brookes posted a decent improvement to claim the 11th best time, going almost eight tenths quicker than he managed during free practice yesterday.
