Shane Byrne has maintained his top spot during free practice two and was able to build a gap between himself and the chasing pack, while his PBM Kawasaki team-mate Stuart Easton held on to the squad's 1-2 on the timesheet by edging ahead of Milwaukee Yamaha's Josh Brookes.
The defending MCE British Superbike champion lapped within a fraction of the 2014 pole position time set by Ryuichi Kiyonari as the majority of the BSB field chipped away at its FP1 times.
Byrne's quickest lap, a 48.186s, is just 0.064s off Kiyonari's pole position, while local rider Easton kept second place from Brookes, but the pair were nearly a third of a second down on the four-time BSB champion on the short 1.2-mile Knockhill circuit.
Tyco BMW's Michael Laverty continued to quietly go about his work by taking fourth spot on the timesheet ahead of Christian Iddon on the Bennetts Suzuki and a resurgent Peter Hickman on the RAF Reserves BMW. Surprise package Luke Mossey and Quattro Plant Kawasaki maintained a top ten spot in seventh ahead of Buildbase BMW's Kiyonari and Be Wiser Kawasaki's Danny Buchan.
James Westmoreland got the better of his JG Speedfit Kawasaki team-mate James Ellison for the first time this season to round out the top ten, with Richard Cooper 11th and Ellison 12th.
However, the top 20 riders are spread by just over a second which demonstrates how tightly-contested qualifying is expected to be tomorrow.
The second free practice session began with a number of riders suffering problems, as Cooper and Dan Linfoot crashed in separate incidents unhurt, while former BSB championship leader Ellison stuttered to a halt with a technical problem on his first out lap.
Midway through the session Byrne was able to improve his FP1 time with a 48.452s while his PBM Kawasaki team-mate Easton and Milwaukee Yamaha's Brookes closed the gap to under a tenth of a second.
With just over a quarter of an hour remaining Brookes slightly overdid it in his pursuit of the PBM Kawasaki pair and suffered a low side crash at the hairpin, but the Australian was able to pick up his Yamaha R1 and return to the pits.
As the session entered the final ten minutes Honda Racing's Jason O'Halloran took a trip off-road at turn three while Be Wiser Kawasaki's Chris Walker had a similar issue at turn seven to bring a premature end to their day. But for the defending BSB champion the best was yet to come and looks in unbeatable form after his double victory last time out at Snetterton.
