Kirton rider Ben Wilson endured a frustrating weekend at Thruxton as he was forced to pull out of the first Superbike race and the team withdrew him from the second race because the bike had become unstable.
He was expecting to have to find a set-up for the Gearlink Kawasaki Superbike as this was its first visit to the Hampshire circuit so the team had no data to help them.
But Wilson was unable to record a fast lap time and, having been placed on the eighth row of the grid for the start of race one on Sunday, he retired to the pits after completing just four laps.
Team owner and manager Michael de Bidaph said: “There was no alternative but for Ben to retire from the race.
“We had a discussion and decided it would not be in Ben’s best interests to try to ride the bike in race two.”
Wilson said: “This weekend has been so frustrating, it didn’t matter what we did with the bike it just didn’t respond.
“I did try to ride it in the first race but it wasn’t happy and tried to throw me off at every opportunity.
“I was going backwards and just about last so the best option was to retire.
“We will have a new frame in place for the next round and we hope to find some improvement when we get to Oulton Park.”
