Leon Haslam believes World Superbike should take a cautious approach to any future rule changes, given the success of the championship so far this season.

Crash.net asked Haslam if he thought WSBK should consider adopting some of the rules now present in the British Superbike series, where Haslam is a former title runner-up.

BSB has run a 'Showdown' system since 2010, where the top six riders start the final three rounds separated only by podium points, while this season has seen rider aids heavily restricted through the use of a standard ECU.

But with the racing so closely contested in WSBK 2012, Haslam feels it is hard to justify any major changes.

"There is a lot of speculation about World Superbikes rules... I know a lot of the decisions that have been made so far are down to cutting costs, to get bikes out there and keep the racing close," replied the factory BMW star.

"For me the racing is as fast and as close as it ever has been - with six manufacturers and all the different winners that we've had.

"We're only five rounds in and we've had five manufacturers winning. Six or seven guys are also really close in the championship. You can't really get much better than that."

The one area that Haslam feels might need reviewing is in terms of the one-bike rule.

"For sure the one bike rule is sometimes a little awkward and we need to evaluate if that is really a cost-saving benefit," he said.

Reflecting on the racing seen in the leading motorcycle championships this year, Haslam gave an upbeat assessment:

"I follow BSB and MotoGP as well as World Superbike. I love all racing. At the minute all three championships are having some exciting racing. So it's all good."

Haslam is sixth in the 2012 WSBK standings after losing out on victory at the very final turn during last Sunday's thrilling Donington Park round.
