Nice piece but not for BMW motorcycles
Solid filter wrench. My bad for not checking the fit. Way too big for BMW filter 11 00 1 341 616 on my motorcycle. Turns out I had one that fits anyway. How dumb was that? I didn't get to try it on anything but four stars for appearing to be a good solid tool.
