The 2004 KTM 85 SX uses 0.35 liter of motorex topspeed 4T 15-50 Weight , also ( ='s 11.8 oz) (='s 0.36 quart) ( ='s 350 milliliters CC ) ( ='s 0.73 pint) (='s 1.47 cup) ( ='s 23.6 tbsp) Notice the top arrow is your overflow screw, just unscrew and level bike and fill with oil very slowly untill oil starts to come out the screw hole, OR if you measure it right to begin with most probably will not to need the overflow screw, The bottom arrow is the oil drain bolt, sometimes has a hex key inside of bolt or may just look like an ordinary bolt , if there is any other questions about your ktm you may post your questions below, thanks, I can help with many other size and years ktms aswell,
