Good point about ABS. That’s the other biggie that happened back then.
So I agree — EFI and ABS and nothing more.
I might hedge a little and admit that I wouldn’t mind having airbags in my classic ‘80s cars, but on the other hand I definitely prefer their minimalist steering wheels with no pudgy bump in the center.
I don’t know how familiar you are with BMW bikes but they have a unique front suspension that almost eliminates front end dive. This combined with huge Brembo brakes makes for a system that will bang your eyeballs into your helmet shield and still give you complete control.
