Sibling comment has good points. My go-to was years back when HD put a single disc with a single piston caliper up front. Anything Japanese at that point put two discs, usually multiple pistons. Some sport bikes were running monster six piston calipers.

And there’s that fat-ass Harley hauling it’s bulk down with that one scrawny disc and anemic caliper. ‘cuz, you know, style. Always seemed like a lawsuit waiting to happen. Can you imagine a car manufacturer saying, “the braking system is not even close to state-of-the-art because it wouldn’t look good”?
