I’m a glutton for punishment. For better and for worse I now own my fourth Italian motorized vehicle, a Ducati 999 motorcycle. It’s always amusing to me when I find examples of anomalous technical data that could only be proffered by Italian engineers. To wit, I wanted to verify the proper tire pressures on the bike. The user manual I have lists the pressures as such:
If you convert these to PSI, you’ll find that there’s about a 7% difference between the two values. Close enough for Italian engineering.
