Glenn Irwin has split from Quattro Plant JG Speedfit Kawasaki in the Bennetts British Superbike championship by mutual consent.

The former BSB race-winner has endured a tough time getting up to speed with the Bournemouth Racing-run squad, despite finding instant success in road racing with a lap record and Superbike win at the North West 200 in May, and missed last weekend’s Snetterton round with an eye problem.

But with a pair of ninth-place finishes acting as his best results in BSB this season, Irwin and the Kawasaki squad have confirmed a mutual separation after just six rounds together.

“Glenn has a long history with Kawasaki, riding for us in a multitude of classes and achieving numerous successes along the way,” Ross Burridge, Kawasaki Motors UK Senior Racing Coordinator, said.

“We signed Glenn on to the team with the hope of retaining the British Championship title this year, but for a myriad of reasons it hasn’t worked out.

“I would like to personally thank Glenn for his efforts in trying to turn his season around and also for his tremendous achievement at the Northwest 200. Best of luck in what the future holds for you Glenn.”

Quattro Plant JG Speedfit Kawasaki are yet to name Irwin’s replacement ahead of the next BSB round at Thruxton (August 2-4).

Hector Barbera would be considered a front-runner given his impressive performances acting as the team’s stand-in so far this season. The Spanish rider finished sixth on his BSB debut at Donington Park in May and has picked up 31 points from three rounds.
