MotoGP is always an arms race. A contest between manufacturers to try to make their bikes go faster. The trouble is, of course, that once you have made your own bike go faster, your rivals turn around and do exactly the same. You find yourself back where you started, or worse, the only difference being that everyone is another tenth of a second quicker, and finding the next tenth is now exponentially more difficult.
Ducati are the current masters of this, though it wasn't always this way. In the past, the Desmosedici was an intransigent beast that only a few riders – or rather, one rider – could wrangle into submission. Ducati have turned that around over the past decade, and now, where they lead, others follow.
So with two years of enforced inaction due to the restrictions imposed to keep costs down during the Covid-19 pandemic, the Jerez test saw Ducati unleash a pent-up torrent of new parts and ideas. Many of the new development parts have been discussed here already, including the new fairing, the new engine, and the extra long exhaust tried on the bike that might become the GP22. (For a full analysis, see my post-Jerez test round up).
