Sports bikes are probably the hardest to maintain and repair.
It stands to reason that the simplest bikes to maintain are the simplest. That would mean small single-cylinder machines like moped, scooters, etc.
Modern bikes, especially Japanese bikes, have gotten more and more complex over the years, and a large part of the reason for this is that they are so reliable that the complexity isn't a problem. So long as you keep up with oil changes, valve adjustments, etc., a modern Japanese bike (especially water-cooled) will last a long long time without the need for much work.
One of my bikes an ST1100, and it has to be one of the most complicated bikes ever made. You take off the plastic covers and it looks as complicated as a modern car under the hood. But the bike has 65k miles on it now and it's never needed anything but a new battery and a radiator cap. We even checked the valves, that was about a 1-hr operation, but it didn't need adjustment.
A sport bike would be the same, unless you're abusing it. The problem is that these bikes are made for abuse. The real sportbikes--GSX-R, CBR, R1/R6--are almost like racing bikes for the street. They have a narrow powerband, up towards the redline, so if you ride it hard you're revving it up all the time and it's going to wear faster. The bike will last a long time if you ride like a 'grownup', but that's not how these bikes were meant to be used. You can totally thrash a bike like this in 20-30k miles, but reasonably ridden it should last 100k miles no problem.
