These Steam Punk BMW emblems of 70 mm diameter are a nice addition to an aluminium tank or painted specimen. It is a brass emblem. It is untreated and when you put it on like this, it will turn into a nice colour. This gives the emblem a nice patina. You can also treat it with a transparent lacquer if you don't want this. 

They are made by hand during an intensive process. Just look at the pictures. You buy a set of two. This is not for everyone, it will give your bike a unique look that hardly anyone else has. 

Fits numerous styles: BMW, Custom, Patina, Vintage, Industrial, Steam Punk, Metal, Raw, Brat,...
