O'Halloran top of the Australians in sixth during Superbike practice.
Shane ‘Shakey’ Byrne lapped under the existing lap record in the opening free practice session for the Bank Holiday Monday third round of the MCE Insurance British Superbike Championship.
But it was Tommy Bridewell who proved to be the rider for all conditions with consistent performances in both the dry and wet.
PBM Kawasaki’s Byrne saved his best for last in the morning session to post a flying lap of the Cheshire circuit in the closing moments of the session to move fastest, with the four-time title-winner 0.351s ahead of Tyco BMW’s Bridewell.
Ryuichi Kiyonari is eager to put his bid for a fourth title back on course, setting the third fastest time in the dry on the Buildbase BMW ahead of Stuart Easton on the second PBM Kawasaki.
Brands Hatch double race winner James Ellison held fifth place as the JG Speedfit Kawasaki rider bids to close the six point deficit on Byrne in the standings in Monday’s two races.
Rain during the afternoon session spoiled the chances of any improvement in lap times, but Australian Josh Brookes mastered the damp conditions on his Milwaukee Yamaha to head off the challenge of Howie Mainwaring on the Quattro Plant Kawasaki and Bridewell in the final minutes of the session.
Byrne played a waiting game to sit out most of the second session, but with just under 15 minutes on the clock he headed out on track to set the sixth fastest time in the wet conditions.
Top of the Australians overall was Jason O’Halloran in sixth, from Brookes in seventh, Billy McConnell 13th, Josh Waters 19th and Broc Parkes 22nd.
