Troy Corser has taken just six events of the 2010 World Superbike Championship to surpass his points' total from the 2009 season after another pair of solid finishes at Kyalami.

The Australian ended his first season with the burgeoning BMW team with a total of 96 points, but having already stood on the podium with a run to third at Monza, he is now classified on 105 points with seven events remaining.

Despite this, Corser didn't enjoy his most prosperous day of the season with a run to 12th and seventh positions, the former champion blaming a lack of grip for his failure to get on terms with the front runners.

"It was just one of those frustrating inconsistent race days," he said. "In the first race I had about zero grip after just a few laps. After that it was a struggle just to get round the track, but I wanted to finish and pick up whatever points I could.

"I had virtually no feeling from the tyres and I knew I would crash if I pushed any harder, so I cruised around as best I could. The tyre I used in race one was the same as one I'd used in practice, but it just didn't work.

"When we checked afterwards, we found out that it was a tyre from 2009, so it's possible that it had been on and off tyre warmers and so maybe was not in as good condition as it should've been. It's funny, but the tyre we used in practice was a 2010 tyre, and what we had for race one was a 2009 tyre!

"We changed the bike a bit for race two and also tried a different (B) tyre and I noticed an improvement straightaway. The bike was still spinning, but this time I could feel what was going on and could push the bike much harder. I made a good start and saw a gap that would get me through to the top four, but at the last minute the two guys in front of me closed the gap and I had to ease off or possibly touch them.

"Today the engine felt quite good and the braking was also good. I sort of think that our grip problem is more a mechanical problem than electronic and maybe we need to work more on the chassis.

"Also, today the throttle response could've been better - more smooth - and that would've helped a lot. All in all, a bit of a frustrating weekend, with one bad race and one good. But, we've learnt a lot this weekend and now we can take all this info and work on improving the bike for the next race."
