Britton will partner Finnegan in the Ulster Grand Prix on Saturday week around the Dundrod circuit.

The Enniskillen rider will be on the competitive Honda previously raced by John Laverty in the British Superbike series.

"I'm open to offers for the other classes at the Ulster," said Britton.

Britton left the DMRR team following a disagreement with Co Armagh owner Des Moore. "There were a few things we did not see eye-to-eye on and if you're not happy there's no point in staying," said Britton.

Moore said Britton "has his own reasons for this split" but added that he had ridden Yamaha bikes in breach of his commitments recently.

"I am saddened that Richard has chosen not to pursue his road racing dreams with us," said Moore.

"Team DMRR wish Richard all the success his abilities warrant in the future."

Ian Lougher will continue to ride for the team for the remainder of the season, with Australian Cameron Donald as his new team-mate.

Meanwhile John McGuinness has completed his stable of bikes for next week's Ulster Grand Prix.

McGuinness will ride a Honda Racing 600cc machine in the Supersport class and an R1 Yamaha supplied by Image Motorsport in the Superstock event.

This is the machine normally ridden by Ryan Rainey in the British Championship.
