Jonathan Rea says he cannot risk losing ground on the leaders after posting a pair of modest top six results on home ground at Donington Park.
The Ulsterman struggled with set-up on the Castrol Honda throughout the weekend, but while he was content with fifth in race one after becoming embroiled in a time-consuming tussle with Noriyuki Haga
and Max Biaggi, he was concerned he could get no higher than sixth in race two when he was 'on the maximum'.
Already 53 points off Carlos Checa
at the top of the standings, Rea admits he cannot afford to be satisfied to be just 'on par' with his rivals at this stage in the season.
“We got through the weekend OK but five and six is not what we came here for and, by my own standards, “OK” is not good enough. I've tried my best all weekend but I got duffed up a bit in race one and maybe could've finished a bit higher.
“In race two, I didn't make any mistakes and rode as well as I could so it was frustrating when the other guys came past. They seemed to be able to ride away from me quite easily while I was on the maximum. We tried to use the softer tyre during the weekend but it tore up after ten or 12 laps so I'm not sure if it would have made any difference.
“We've got some work to do, I think – especially on the electronics side of things to get driveability off slower corners. Luckily for us, Assen hasn't got the stop-go slower section that we have here, so I'm looking forward to getting there for a bit of flow.
“At the end of the day we were sort of 'on par' here, but we need to be better than that, especially at this stage in the season. We don't want the guys at the front to be opening this much of a gap, so we need to be on it from the next round.”
The next round of the season at Assen sees Rea return to the scene of his double victory in 2010.
