I guess we’ve been spoiled by BMW
If by "Spoiled" you mean manufacturers fixing their own fuckups then yes.
Most are run by bean counters who want to cut the R&D budget, cut the materials budget, cut the labour budget, and then when things go wrong, like chocolate camshafts they just hope it will either:
A: Fail outside of warranty period
B: They can blame the owner for the problem
Not sure what they are like now, but I almost bought a Triumph many moons ago, but the forums at the time had lots of horro stories, engine fails "You must of run it low on oil mate", Head Bearings shot cos they never greased them in the factory "You must of wheelied it mate" and that sort of guff.
Not so sure about Jap stuff as it typically does not go wrong, in late 80s I worked at Honda dealer and we rarely had a claim, and never had issues getting stuff done under warranty, but a couple of years ago I bought an 18 month old / 3,000 mile CB500X with rusty fork stanchons and was told "they all do that sir", "it must of got wet sir" and no chance of getting them on warranty....
....Also highlights the decline in quality, it was replacing a 60,000 mile 14 year old 650 V-Strom that had no such corrosion issues,and I had commuted on it for a couple of years, certainly seen as much rain as the almost new Honda!
