I think it's different when we start comparing cars with bikes. And I don't have any experience with modding bikes. I do agree with what you're saying though, however in the end that's not how it turns out. I think you're over thinking it a little, because the same can be said with any mod e.g. HFC, CBE, Headers, pretty much anything that will gain more HP. I can now say that Nissan did massive R&D for the 370Z at it's current spec. Adding another 30+ HP can translate to more strain on the drivetrain, tranny, axles, etc...which in the end will damage the car in the long run. But hey! to each his own.
