A rather scruffy stock part is shown below for contrast....
Brand new, polished stainless steel, perfect. OEM part # 0177-40-020, one each required at either side of the swingarm pivot. The plugs install perfectly with a little WD40 and the tap of a mallet. A supplied o-ring holds them in.
I believe these parts will fit just about ALL Ducati singles. This listing is for ONE PAIR.
