0.75 litres
ktm recommend you use a 10w30 oil for the 2 stroke and you will need 0.75 litres make sure you get all the old oil out though otherwise you will overfill it and that can be as bad as under filling it ..
KTM has a section of their site where electronic copies of their motorcycle manuals can be downloaded for free. They offer most models and many years.
It depends on what year, model and is it a 2 or 4 stroke. See KTM tech bulletin for 06 models below.
