Officially listed in Pro Italia's catalog as "Ducati OEM Special Screw," what on earth could make a screw so special that it'd cost $300? Just as importantly, why do you need eight of them?
Turns out the screw is needed to hold Ducati's race-spec engines together, specifically the 197 HP 989cc V4 of the Ducati Desmosedici RR MotoGP replica and the 1199cc v-twin of the $40,000 Ducati 1198 R.
The screw itself is made from heat-forged Japanese steel and bolts the connecting rods together and is a Ducati Corse item, which means it's a specially made factory hop up part.
