All smallblocks since 2017 use valves, piston rings, and other engine parts from China. When Vagrent's went tits up I called Tech Rep for Piaggio that used to hang out in our shop, lives down the road here 25mi.
Could be, but sounds like a lazy claim to me. If I look up 1A015607R and check the country of origin on sites that list it as required for international shipping duties, it lists Italy. Doesn't necessarily mean that's accurate or reliable, but just one spot check that is turning up Italy rather than China. I'm sure there are parts made in China, especially common components not unique to the bike. When I dug into the headset bearings on my V7 850 they were a FAG (Schaeffler) bearing inscribed Vietnam, but possibly with an outer ring from China.

Metallurgy, manufacturing process, quality control, and supplier requirements do. Vehicles sold in the EU do a decent job weeding out some of the rubbish we can buy in the states with their Conformity of Production standards set out under European Whole Vehicle Type Approval.
