Seems still depends on design and each engine can have this "threshold"... On my car (x16xel engine) motor starts a bit consume oil if I keep it constantly over 3000rpm's.
On TA I mostly keep not more than 5000rpm's, oil is not consumed noticeably. And I change oil like on car- around 10 000km's or once per 2-3 years, which comes first. Old oil from engine is quite clean always. So, I don't see reason to change oil more frequent, except when most riding is done in city or heavy offroad. But I ride mostly in "light" mode around 90-100km/h on highways
