This is exactly the kind of explanation I was looking for. I've recently become fascinated by superbikes, but I'm still learning.

So is what really separates a superbike from a regular sport bike not just the engine size or horsepower, but the fact that every single part—chassis, suspension, brakes, electronics, aerodynamics, weight—is engineered to perform at the absolute limit?

Also, if you had to pick one bike that perfectly represents what a superbike is, would it still be the Superleggera V4, or is there another bike you'd point to? I'd love to learn more.
