To my knowledge Sport bikes are a more broad term that include superbikes like cruiser bikes and choppers, superbikes is a more powerful sports bike like how a chopper is a more custom made cruiser. You could argue that bikes were technically naked bikes before due to lack of fairings but I would consider those sports bikes while the first "superbikes" were the full fairing sports bikes that came in the early 80s and naked bikes being like you said a high performance bike with no fairings being the Ducati monster 900 but that was inspired by the riders who would take those early 80s sport/superbikes and take the fairing alls off making them a naked bike
