Howie Mainwaring will join up alongside John Hopkins at ePayMe Yamaha at Cadwell Park in place of Broc Parkes who is away competing in the final round of the World Endurance Championship.

Mainwaring split from Smiths BMW after round six at Thruxton having failed to gel with the bike and is set for a one-round outing with Parkes returning to action in the MCE British Superbike championship at Oulton Park in September.

The former BSB race winner is relishing the opportunity to race the Yamaha R1 on one of the most demanding circuits on the calendar.

"You can only imagine how happy I am to have been given this opportunity," Mainwaring said. "I have tested the Yamaha, although not the one I am going to race at Cadwell Park and it really seemed to suit my style.

"I am excited about this chance to race with Tommy Hill's team and although Cadwell Park is a bit quirky, I have no pressure on me so I can just build up through the weekend. I am really looking forward to Cadwell Park and doing the best job I can for the team."

Team owner Tommy Hill has welcomed Mainwaring with open arms and is confident both of his riders can enjoy productive outings, while Hopkins continues to regain his speed after his return from injury which ruled him out of the Snetterton and Thruxton rounds.

"We wanted to have both ePayMe Yamahas on the grid at Cadwell Park and with this as a one off appearance; we have decided to give Howie the opportunity," Hill said. "He has had a difficult season and he can go into this event with no preconceptions or pressure.

"It is great that we were able to test with John this week and he is continuing to rebuild the strength in his shoulder and we are looking to put the ePayMe Yamaha back where it should be. As a team we are ready to take on the next event and having a strong weekend."
