men (´n girls) ?
"don´t mix in mind apple and oranges" - both are fruits but with dif. tastes
the milage for oil change at the hayabusas differ depending of their "year"
´99-´07 & ´8-´14 - all official suzuki maint. tables for the busa all say every 6000 km / 3750 mi
and
at ´15 and later they moved to 12000 km / 7500 mi
thats a fact
now my guess is that the oil´s quality increased over the years and watching the identical quality in all materials of the engine
everybody should can move to that longer interval
IF
he/she doesn´t use the bike only for a mile or two to buy the bred at the bakery and return home.
THAT behavior shortens, in my view, the interval down to max the half of the old intervall of 6000/3750
to be save to get all kondens-water etc. out of engine.
on the other hand -
if one allways runs the bike for 60/40 - one run - and more , the intervall can be the 12k/8k like at the 2015´s ..
BUT
all that only at usual busas!
the turbo´s differ - there i would, safety first, change oil after 3500 km / 2000 mi to keep the oil buffered turbo axle bearing in best shape.
at least that's what I strongly recommend to my buddy with his ´01 gen1 turbo, that he runs at up to 1.2 bar / 17.5 psi at our not-speed-limited autobahn (over 340 kmph - gps messured).
