Immediate thought is my Kawasaki 500 H1 in 1975......crazy motor but nothing else. Brakes? Handling? No need for that shit.....just point the fucking thing and hope for the best!
Also any Suzuki I've had......strong engines but the rest of it tends to be cheap and nasty with tacky plastics, sloppy wiring, and bad welds! Accompanied by rust! Lots of it!
The Brits I had in the early 70's were shit motors, but the rest of the bike was shit as well! They got the balance right for sure!
