Honda CBR400RR NC23 Tri-Arm (88-89) oil pan / sump complete with oil drain plug and bolts. There’s a minor chip to the front edge of the fin casting adjacent to the oil drain plug, probably caused by a slipped socket or spanner in the past, otherwise in good usable condition.
Removed from engine number starting NC23E-10214… from which all engine parts appear to be okay, presumably the CBR400RR NC23 donor having been broken for parts due to accident damage.
