Sport bikes are lighter than standards, often have more power and better suspension. In real world riding, the difference is negligible, but on the track they are definitely superior. If you ride within the law, a standard like the FZ1 will handle any road just as well as any sportbike, and be a lot more comfortable in the meantime.
The maintenance for a standard will be no worse than a cruiser, with the possible need for periodic valve adjustments and chain maintenance, that a cruiser may not have. Not enough to matter, in my opinion.
