Complexity is starting to go that way with bikes too, and I suspect euro 4 & euro 5. Plenty of drive-by-wire bikes now, with IMUs and other tricky bits, and some of the few really simple ones remaining (new) wont' make the new emissions standards (e.g. moto-guzzi is getting more complex). But you are right, if you stay away from the performance engines there is a lot you can do, and it's easy to get at.
