Very much a cloak and dagger affair, it is always fairly entertaining to read the information that the manufacturers release regarding their MotoGP machines. Despite the fact that these are some of the most drool-over motorcycles on the planet, by rule of thumb the factories publish only the most general technical specifications possible.
If a company like Ducati thought they could get away with it, the release for the Ducati Desmosedici GP13 technical specifications would read something like “a racing machine with possibly two wheels and an engine” when disclosed to the press and public.
Part of the subterfuge is disclosing misinformation, and despite the fact the Ducati Desmosedici GP12 possibly did not have a full-liter displacement, Ducati Corse listed the machine as having 1,000cc of displacement, quoting the same figure this year. So what is the big deal, right?
Well for starters in 2012, we saw Ducati admit to having a seamless transmission (DST), a quick-shifting gearbox of its own, which was not too dissimilar to the HRC unit that got outed at the start of the 2011 season, and was rumored to give an extra tenth of a second per lap at certain courses in shift times, not to mention the added ability of shifting gears while at full-lean.
For 2013, Ducati’s confessions are limited to an additional 5hp over the GP12, though the actual peak figure possible is likely much higher than the quoted 235hp, and varies from course to course. The suspension from Öhlins also seems to have advanced for this coming season, and is quoted in the press release as having a “new factory evolution damping system.” Lastly, the GP13 is also sporting three more kilograms of weight, per the new MotoGP rules.
