DUCATI DESMOSEDICI GP7

[NarendZORCE]

Following on from the most promising season of the Desmosedici MotoGP project, Ducati and Shell have been hard at work to design and optimise the new 800cc Desmosedici GP7 for the 2007 season.

For 2007, the MotoGP World Championship entered a new era, that of lower capacity 800cc bikes, designed to halt the ever rising speeds of these competition machines. Another significant change is the reduction of fuel tank capacity by one more litre, giving a total capacity of 21 litres to last the full race distance. Both these changes have required significant input by the engineers to ensure that the bikes comply with the rules while remaining competitive throughout the season.

For Shell's part the rule changes have meant looking at the design of the fuels and lubricants used in the Ducati's high-revving V4 engine � this was done in collaboration with the Ducati engineers who were busy designing the new lower weight and more compact 800cc engine. The change of engine capacity has also meant a redesign of the frame and aero package on the bike to optimise the performance.

Shell Advance has always played an integral part in powering and protecting the desmodronic Ducati engines. Over the last few seasons, the blend of oil has been optimised and Shell Advance L6442 has been the product of choice due to its unique Friction Modifier technology which has meant the liberation of more power while maintaining its protection properties throughout each session on the track.

Shell Racing V-Power also plays a key role in the Desmosedici�s performance, in fact Shell Racing V-Power RD0502 has been so successful in power production in MotoGP that it is now used in the production based Ducati 999 F07 World Superbikes. While new for 2007 is Shell Racing V-Power PR2772, a fuel economy blend of fuel aimed at helping Ducati combat the challenges of the smaller fuel tank required by the rules, while minimising power loses to ensure non of the legendary top speed is lost.

Oh Yeah! Feel the Rush, it's like... WOW!
May the (Mass x Acceleration)-F+Z be with you...

The Ducati is one of, if not the fastest, bike in a straight line. In the first MotoGP race of the season, Stoner just blew past Rossi on the straight. The Yamaha probably handles better in the twisty sections of the track.

Istanbul is this weekend, another track with long straights. Ducati domination again??

I like the Ferrari F1 style paint scheme on them

Marlboro is Ducati's title sponsor, just like for Ferrari. Hence, the similar paint schemes.
