Jonathan Rea says Kawasaki Racing Team will run a thorough investigation into the mechanical issue which forced him into his first retirement of the season and saw his World Superbike championship lead slashed by team-mate Tom Sykes.
The defending champion had been battling for the lead in the restarted race two until he ran wide and off track on lap five before stopping a lap later with a problem which caused his first point-less race of the season.
With Sykes maximising his opportunity with victory in race two at Laguna Seca Rea has seen his World Superbike championship lead cut from 71 to 46 points.
Rea says he was confident of another strong result before running wide and picking up a problem and is keen for his squad to discover what his stop was caused by.
“To not finish is disappointing because up to that point I felt so good with the bike,” Rea said. “Even when I got stuck in some traffic at the beginning I was able to close down the gap to the leaders. I feel it was one more race we could have really capitalised on, but this is racing sometimes.
“We need to analyse everything with the bike. When I went wide in turn seven I rejoined the track and it seemed I had a problem. As soon as I closed the gas the rear was locking and I heard some noise.
“I carried on through some corners, arrived in turn one and it was really locking a lot. Then in T2 something was wrong so I pulled in.”
Despite accepting the bitter blow Rea – who suffered only his second mechanical failure in 44 World Superbikes races since joining Kawasaki in 2015 – feels the two-month summer break has come at the worst-possible time as he is eager to make amends straightaway.
“We have to take the rough with the smooth because we have had a really good run so far, but it is a frustrating way to go into the summer break,” he said. “I wish the Lausitzring round was next weekend because I feel really good with the bike and that is a huge motivation for me.”
World Superbikes will now take an extended summer break and resume for round 10 at the Lausitzring on the 16-18 September.
