Yeah I know, old post etc..... so maybe those who indeed changed their 230's oil only at 2500 Km - or 5000?

- will have seized properly by now.
Read the Owners Manual, and if you don't have it - I do!
It says "change oil every 1000Km" - every thousand kilometers !!!
That, uh, every 6 or 7 tanks full?
This bike has no oilfilter, only a centrifugal one - which you need to clean every 2000 Km!
So, the mentioned 5000 Km means 5 oilchanges plus 2.5 filtercleanings.
It takes 1 liter exactly, and indeed the dipstick is not in but on the thread, bike held level.
Use it, don't..
