Leon Haslam still regards the FIM MotoGP World Championship as the pinnacle of motorcycle racing despite competing in the FIM Superbike World Championship in 2009.
The Stiggy Honda rider has been impressed by the resurgence in World Superbikes which has seen the grid swell for this season as the series goes against the downturn in the world economy.
However, he thinks the status as the number one series will switch between the two championships from time to time.
Haslam said: "I've always grown up with the fact MotoGP is the elite of bike racing. It still is. It's the Formula One of bikes.
"World Superbikes is totally different to MotoGP. Yes, it is bike racing, but MotoGP is all about prototype bikes.
"They've also gone to a one-make tyre, which I think will be good for them. It's another factor which evens it up.
"But it is two different forms of racing, and it always swings back and forwards."
