These mirrors are 10mm and come with the adapters to install on many motorcycles like the CF Moto V5 and V3 as well as the Cleveland Cyclewerks bikes. Not plastic but real hard heavy metal.
First thing to do when you get your V5 is upgrade mirrors to a good looking mirror you can be proud of, why they put those stock mirrors on a cool bike I do not know, I have these on mine and they work and look great.
These state of the art custom mirrors are cut from the same mold as our turn signal mirrors - but they do not have the running light and turn signal functions. They feature an oversized swivel ball for superior locking ability. Both mirrors are 5"(l)x2-3/4"(h). Sold in pairs.Note:
