Local men Alastair Seeley and Michael Laverty will be chasing British Supersport and Superbike titles respectively this weekend at Brands Hatch in Kent.
The final round of the BSB series offers up triple-headers for both the middleweight and Superbike divisions, with qualifying and race one action for both classes taking place today.
The final two races for both classes are tomorrow and there's a distinct possibility Northern Ireland will have one, or possibly even two, British champions crowned.
Clogher's Keith Farmer (National Superstock 600) and Antrim's John Simpson (Supersport Cup) have already been honoured as the top riders in their classes this season.
After chipping away at main rival Ben Wilson's 50-point lead, Carrick's Seeley goes into the final three British Supersport races with a 14 point advantage over the Gearlink Kawasaki man, on-board Hector and Philip Neill's Relentless by TAS Suzuki.
Seeley topped the early practice leaderboard during yesterday's Supersport session, impressively shaving three tenths of a second from the Indy Circuit lap record.
The action moves to the full GP circuit for qualifying and race action today and tomorrow.
"I'm confident coming into the weekend and I know what has to be done," explained Seeley.
"I'm sure it will be exciting for the fans as, like the Superbike class, it will probably go right down to the final race," he added.
One rider hoping the Superbike class does go right to the wire is Toomebridge's Michael Laverty.
Laverty is fifth in the standings, 44 points down on leader John Hopkins, and faces an uphill battle. But it's not impossible.
Laverty said: "The pressure is off me now and I can come into Brands Hatch feeling confident."
Laverty was second quickest of the Superbike competitors yesterday behind Josh Brookes.
