Brand new, still in the box mirrors for motorcycle (can go on streetbike, dirt, or ATV). Conventional metric threads. Even though they are sporty (like for a streetbike) I use them on my on/off dirtbike because you can rotate them 180* and make them 'tighter' on your bike so you can fit between tighter spaces, or back out if you are on the open road; compare #3 and #4 photos for an image of what I am talking about.
