That was the 70s. By the 80s, things had changed. The tank and frame were steel, but the fork sliders were aluminum (and painted), the engine was painted aluminum, the frame fittings like the rearsets were painted aluminum, the rear grab handle was painted aluminum....

Lots of painted aluminum on that bike - a 1986 Nighthawk S, like mine. The amount of aluminum on bikes would increase as time went on as the sportbike power and weight wars went on. Most of it would end up clearcoated or painted black at the factory. And the paint didn't fall off it.

To say nothing of the now exceedingly common painted aluminum wheels on every modern non-retro motorcycle. The paint hasn’t come off the aluminum wheels on either of my bikes, it hasn’t come off the painted aluminum engine parts, it hasn’t come off the aluminum rearsets, the aluminum brackets, the aluminum master cylinders, the aluminum control perches, etc., etc.

The problem isn’t aluminum. If it was it would have shown up by now for every maker.
