hi down under
that way i never would prescribe the oilchange
my experiances are : the max mileage belongs to the way one uses his bike
two extremes :
1. only ´n allways for so to say getting a bread or so at the bakery around the corner, even 4000 km between two oil changes can! be too much
2. riding allways distances over 30-40 km and more - one way - and the oil can stay in for around 8-9000 km
the oil change every 12000 km that suzuki writes in the new maintenance sheet since 2015 for me personally is too long at all.
I think nothing of the principle of all long life oils (30000km).
e.g.: on my audi 3.0 diesel for example i change the oil every 10,000 km, but at the latest after 12,000 km
the way to my workshop is 30 km one way (ten of em inside town - the rest at country roads) and over that mileage even the oil gets his working temp. of 85-90°C , if it is not winter time with enduring temps under let me say 10°C .
and
i have no clue what the warranty for/at a brand new bike (vehicle) means in the us,
but here in germany i recommend allways to do the prescribed services at the dealer while the warranty / guarantee is active.
the only exeption is (in my view) if the owner is a well experianced craftsman with own workshop for a bike.
and
i never heard of bigger issues in the first two years of warranty / guarantee so the craftsman can decide if he goes that risk.
