Byrne, riding for Paul Bird’s Rapid Solicitors Kawasaki team, mastered two safety cars and three extra laps to lead from start to finish and claim his second win of the final round at Brands Hatch.
Only a late move from Tyco Suzuki rider and his nearest challenger for the title Josh Brookes into second prevented Byrne wrapping up his third British crown there and then.
However it will take something spectacular to prevent Byrne becoming British champion with the difference between him in first and Brookes in second now 23 points.
As expected it was dramatic start with Byrne blasting off the line to take the lead at the first bend before the grid lost four riders to a crash.
Mark Aitchison, Patric Muff, Karl Harris and Danny Buchan were all involved in an incident shortly after while Alex Lowes moved into second ahead of Stuart Easton at the start of lap two.
Racing was effectively halted when Tristan Palmer’s tumble forced out the safety car shortly after but it was back on for the start of lap five with Byrne proving immovable.
Lowes was equally as comfortable in second while behind them the relatively unknown Barry Burrell passed Showdown rider Michael Laverty at the start of lap six.
Burrell wasn’t going to be stopped and it wasn’t long before he was in second while he set the fastest lap of the race so far on the seventh.
With the top two seemingly set, attentions turned to Brookes who passed Laverty into fourth at the halfway stage before passing Showdown rider Lowes into third.
Lowes held his hand up moments after Brookes’ pass indicating a problem with his WFR Honda yet he continued racing on, however he did eventually put into the pits.
Brookes set the fastest lap of the race 13 in but the safety car was to come out again not soon after following James Westmoreland’s crash at Clearways.
That bunched the grid together and extended the race to 23 laps with Brookes eventually passing Burrell into second with two laps left.
Burrell went backwards as Laverty came through for third overall with the two other Showdown riders Tommy Bridewell finishing fifth and defending champion Tommy Hill sixth.
