Ducati Desmosedici GP4 - technical specification.
Ducati's MotoGP machine may have made an impressive debut in 2003, but that has not prevented the team's engineers from making changes to its specification over the winter.
More than 60 per cent of the 915 individual components that make up the new D16 GP4 are totally different to those on its predecessor, to the extent that they cannot be interchanged with the previous version.
