Michael Rutter will compete in the Supertwins class at the Isle of Man TT in June for top Northern Ireland rider Ryan Farquhar's KMR Kawasaki team.
Rutter had been in talks with Farquhar over the possibility of also riding in the class on an ER6 at the North West 200 in May, but multiple Irish short circuit champion Kirk Jamison will instead join Farquhar, ex-Grand Prix hero Jeremy McWilliams and former British Junior Superstock 600 champion Jamie Hamilton in the KMR team at the international road race.
At the TT, Rutter will go head to head with fellow winners in the reintroduced Lightweight event, including Michael Dunlop, Cameron Donald, Adrian Archibald and Ian Lougher.
Rutter is competing in the MCE Insurance British Superbike Championship this year for the MSS Colchester Kawasaki team.
Speaking about the line-up, Farquhar said: “It's great to have two more riders added to the team and it gives us a great chance of honours at the North West 200 and Isle of Man TT.
"Having someone of the stature of Michael in the team is a terrific honour as he's one of the finest road racers of his generation and it will give the team a great chance of succeeding in the Lightweight TT.
“To be able to have riders like Michael and Jeremy on board the bikes shows just how far the team's come,” he added. “Kirk is one of Northern Ireland's best short circuit racers at present and although the North West 200 is a different ball game, I'm confident he'll give a good account of himself.
“Having four bikes on the grid at the North West and three at the TT is a big undertaking so I'm hoping I haven't bitten off more than I can chew. I wouldn't have done it if I didn't think we could succeed though and all the lads in the team are mechanically minded and able to help out so I'm sure we'll be fine.
“I've been working on the bikes since the end of last year and they're better than what we finished 2011 with, having found some more speed so it's looking really good.”
Farquhar only competed in the Senior race at the TT last season after a crash during practice at Keppel Gate ruled him out of the remainder of the races through injury.
The Supertwins class is being held at both the North West 200 and TT for the first time in 2012.
