The last four rounds of the MotoGP World Championship have seen Dani Pedrosa claim 86 points relative to 85 for title leader Jorge Lorenzo.

Compare that with the opening four rounds of the season, when Lorenzo outscored Pedrosa by 90 points to 65 and it looks like the tide could be turning in Pedrosa's favour.

However Yamaha star Lorenzo still leads by 18 points - with seven rounds to go - and Pedrosa knows he will need bigger gains if he is to finally clinch the premier-class crown.

"We recovered five points, but surely it's going to take us to stay there every weekend," said Pedrosa after beating Lorenzo to victory at Indianapolis on Sunday. "This weekend wasn't easy for Jorge with the bike or the tyres and he was still able to be second.

"So we have a tough competitor and sure 'til the end it will be a very tight fight. But I hope I can continue in the same way until the end and have good luck."

When asked if he felt he was riding at his best this year, Pedrosa replied:

"Well, I don't know, really. But I know I'm doing all I know to be fast. So, yeah, I try every weekend. It's not always easy, but, sure, I hope I can continue like this until the end of the year and keep strong.

"If you look at the points in the last four races, I got one point more than Jorge. So it's going to take, sure, a lot of effort 'til the end. And I have to keep focused all the way."

Honda star Pedrosa is the only rider to score points in every round, with Lorenzo and third in the championship Casey Stoner both suffering one DNF. Reigning champion Stoner is 39 points behind Lorenzo.
