Troy Corser says BMW still has work to do if it is prove a consistent front runner in World Superbikes after declaring himself disappointed with his failure to score a podium in the United States.
On paper, Corser's run to fifth position in both races from 15th on the grid looks impressive, particularly when it is considered the team scored just a single point at the American circuit last season.
Shrugging off the grid position with two good starts, Corser was particularly fast at the start of the second race when he got away in third position, which became second when Carlos Checa was forced to retire ahead of him.
However, while he confidently held on for the first-half of the race, Corser's BMW began to struggle with chatter towards the end, prompting him to be overtaken by Leon Camier, Cal Crutchlow and Noriyuki Haga.
Indeed Corser insists BMW needs to keep improving the bike mechanically if it is to remain consistent and durable to the end of the race.
“In any other circumstances a pair of fifths might have been a good result, but I'm not happy because it could've been so much better today. I made good starts from the fourth row of the grid in both races, though race two was much the better for sure, as I was second going into turn one!
“I was pretty comfortable in second and thought to myself that I could stick there without a problem. Then, at about half race distance, I started to get a bit of chatter. It was controllable, but only if I eased the pace. If I ran at 1:50 or so, everything was OK, but if I tried to go faster my lap times got worse! I had a couple of real front-enders at the hairpins, but managed to stay onboard both times, but I could've easily crashed. Today was very frustrating and that's why I am a bit disappointed.
“Today the tyres were consistent, but our bike lacked top speed, especially compared to the Aprilias and Ducatis - especially the Aprilias! I still think that our problem at the moment is a chassis problem (mechanical) and that's something we will have to sort out back at the workshops.
“There's not going to be an awful lot of time before our next outing, because we have some tests before and after the Misano race, so once again, it's going to be hard to get the bikes back quickly and get the work done in time.
“Hopefully, the team will be able to sort out this problem and then I will be able to push hard throughout the whole race. That's what I am looking forward to.”
