Ryan Rainey is coming out of retirement to race in the last four rounds of the British Superbike Championship. The 25-year-old from Dundrod quit the sport in May, saying he was not enjoying his racing as his team at the time was struggling for money.
But Rainey is returning to ride for the Mark Johns Motors team, with his first outing at Croft on 12 August.
Meanwhile, Lusk's Martin Finnegan will ride for the Mark Johns outfit at the Ulster Grand Prix.
Finnegan will be on board the superbike raced by Ryan Farquhar at the North West 200.
