Stoner tests 2009 GP bike

Aussie ace Casey Stoner has had an early run on the prototype 2009 race bike, the Ducati GP9, at Catalunya during a MotoGP test session.

A major break from past practice or the company is to ditch the steel trellis frame in favour of a carbon fibre unit.

He set a best time on race tyres of 1:42.432, 0.2sec quicker than his race time the previous Sunday. That was topped by a 1:41.533 time on qualifying rubber.

"I'm happy with the way today has gone. The objective was to understand whether this new chassis concept has potential and I'd say that for now it looks to be the case. We were quickly into some decent times using the same set-up as the GP8. We barely changed anything to adapt it to the characteristics of the GP9 and I immediately felt an improvement so that is positive. I'm sure that with more time to work on it we can go much faster, although that is not the current brief. We'll have time to test it in the winter. Tomorrow we'll get back on my GP8 because we have some important tyre testing to do. There is still a lot of the 2008 season left and we want to be competitive."

"We took the decision to allow the factory riders to test the GP9 because it would have been more difficult at a later stage of development and eventually we'd have had to go backwards in certain areas. There are some things that are possible to analyse with data such as in the engine or the cycle part but other areas where it is absolutely essential to have the riders' opinions. So it was important to get their feedback to understand if the choices we've made have been the right ones and to get their suggestions. Some changes we've made to the cycle part could seem more revolutionary than others but in reality we continue to evolve the initial concept that we designed with the GP3. So it's not a change in the direction of development, but another step forward in the same direction. With the 990 the seat supports and the footpegs were attached to the frame. With the 800 they are both completely separate and on the GP9 the front part is even more dedicated to support and the dimensions become more limited. The fact we've used carbon fibre in the production of the chassis is not the most relevant point, it is more the shape that is different from before. Casey's first impressions have been positive. Tomorrow Marco will try it and I hope his feeling with the new bike is better than with the current one."
