Bayliss currently lies fourth in the Superbikes standings

World Superbikes champion Troy Bayliss insists nothing would make him happier than raining on James Toseland's parade at Brands Hatch this weekend.

Current championship leader Toseland revealed this week he is moving to MotoGP next season, hopefully as champion. But Bayliss has other ideas.

"I'd love to spoil the party, that's why I'm here," said Bayliss, who lies fourth in the standings.

"I have a good record here and I want to win both races and home in on him."

With four rounds of the championship left, Ten Kate Honda rider Toseland leads the standings on 305 points.

But with 200 points still up for grabs, Max Biaggi (262), Noriyuki Haga (260) and Bayliss (249) are still well in contention for the title.

Bayliss, 38, admits 2007 has been an "up and down year".

Along the way, the Australian has managed five wins, two second places and one third.

But when things have gone wrong for him - as at Donington, where he crashed and lost a finger - and last time out at Brno, in the Czech Republic, they have gone very wrong indeed.

"My accident at Donington meant I missed two races, which was a lot of points when I reckon I should have had two wins," he said.

"That dealt me a bit of a cruel hand.

"I was a bit injured for the next round, then I really started to come good, we got back to within 21 points, but then we went to Brno which is always a bad track for us. I was taken out in the first race and struggled in the second."

While the opposition may have updated their machines this year, Bayliss is still on the same bike which he won the title on last year.

He admits the bike is "at its end" and says the lack of development has forced him to push the machine to the limit.

"Even last year when I was champion, I had a strong start and the others developed their bikes and caught up," he said.

"This season I've not gained anything but the opposition has got stronger, so I've had to poke my chin out to get results, and I've got injured trying to do it."

But if there is anywhere that can lift Bayliss's spirits, it is Brands Hatch, one of his favourite tracks, and one where he says experience counts for a lot.

"I have a decent record here over the years," he said.

"The track has a bit of character, it's a bit dangerous with lots of ups and downs, there are lots of blind corners and you get a massive crowd, who you can actually hear as you go round.

"You need to do a lot of laps here and you need to crash a few times to learn some things," he said.

"This is the first time Max Biaggi has been here, and I'd be very surprised if he won.

"I've been riding here since 1998 and I've been down on quite a few of the corners. Some things you have to learn the hard way."

Unfortunately for Bayliss, one lesson he learnt the hard way recently was the size of the gap between Superbikes and MotoGP.

In 2003, he moved up to the top class for three frustrating years, before returning to World Superbikes in 2006.

But at the end of last season, having secured the Superbikes crown for the second time, he made a one-off return to MotoGP, filling in for the injured Sete Gibernau at the final race of the season, in Valencia - and won.

"That was a bit of fun for me but also to close the story," he said.

"I tested the first MotoGP bike for Ducati in 2002 and I rode in the last ever 990cc race.

"This time I went there with team manager David Tardozi and my technician Ernesto Marinelli, who I had wanted first time out but couldn't get.

"In MotoGP you need everything working for you, and we went there in one weekend, showed what we could do, closed the book and came home. It was a fairytale ending for me."

Toseland is the latest rider to try and cross the divide between Superbikes and MotoGP, and Bayliss says he certainly has the ability to make a go of it.

"I was a bit surprised when he went Yamaha-way, but I hope to see him do well," he said.

"I know he's got the talent, so I think he can do a good job there.

"In MotoGP they'll welcome him, but he'll be a bit of an outsider.

"He needs people around him he can trust - as long as he has that and the best equipment and tyres, he'll do OK. Otherwise it will be demoralising and a place you can be pushed back a little."

But after a week dominated by talk of Toseland's future, on Sunday more immediate matters take priority, and Bayliss is keen to ensure he is the man whose name ends up in the headlines.

"When you're racing at the point end of the field, you want to win the championship," he said.

"I'm 56 points back with four rounds to go - that's not an ideal position, but I'm optimistic about what I can do on a bike."
