Troy Corser says BMW is still taking 'small steps' towards improving its S1000RR World Superbike contender, explaining this as the reason why success is taking longer than many outsiders may have expected.

Corser fronted BMW's category debut in 2009, making important strides during the second season with two podium results and a pole position, though the manufacturer is yet to register a victory.

Though it has shown flashes of speed during the opening two rounds of the 2011 season, particularly in the hands of Corser's new team-mate Leon Haslam, the Australian insists the bike is still developing.

Pointing out that small improvements are more crucial in order to establish a more consistent base package, Corser is nonetheless confident the bike will be a regular podium winner as the season progresses.

"At times it's been frustrating but we are always going forward," he told Crash.net. "I feel we are starting to understand what changes actually do to the bike, so it's been good. We are moving forward a lot now Leon has come on board. We both want the same things from the bike, which speeds up the process of making changes.

"I hope that we will be standing on the podium regularly. We are not far away and there are some areas we can improve the bike. It just takes a bit of time - we need to take it one step at a time so we don't get confused or lost, which is probably why it is taking longer than many have anticipated.

"But this is the way to do it because you can't make five or six changes to a bike, because you won't know what fixed the problem. I've done this long enough now - you have to make small steps to make an improvement."

Corser is currently 13th in the standings after four races, while Haslam is third.
