Factory BMW rider Troy Corser spent two days at Spain's Valencia track straight after the official World Superbike Portimao tests to carry out more development work on the new S100RR.

After completing 156 laps on race rubber with strong winds buffeting the circuit both days and not enough bikes circulating to lay down enough rubber for good grip, the Aussie declared himself happy with the progress.

"We’ve gained a lot of useful information for the engineers and technicians during these two days and if I had to race the bike tomorrow, I wouldn’t be unhappy at all," said Corser.

"It’s been good to be able to do plenty of laps and now I feel very comfortable on the bike and I can ride it without thinking about it. We found a good set up for the suspension, both front and rear, improved the balance of the bike, the brakes and made the throttle connection more consistent.

"I did a long run of 24 laps this afternoon and was able to do good consistent lap times and felt OK at the end of it. We used standard tyres throughout the test and, if the conditions had been a bit better and more rubber had been down, I’m sure I could’ve gone faster.

"I feel we’ve made big steps here and although there’s still lots of work to do, I’m pretty happy and positive about the next time out on the bike."
