I've enjoyed winning races in both 500cc and MotoGP and enjoyed leading the world championship and contesting it right up until the end.

I've decided to retire from top class racing. It has been an incredible experience and has provided with me some unforgettable moments.

In Malaysia where the front end pushes so much, extra engine braking is really going to help you.

So while I was studying, I rode my Trials bike, then I moved to roadracing.

What the other teams do is something that I can never control, so I just keep focussed on my direction.

I've always like roadracing, but you know how it is in a family when you're young. They thought it was a little too dangerous so I started with Trials riding.

With roadracing, it takes a lot more time and money.
