1. Does exactly as intended
This block off plate although cheep works perfectly. Like the oem mirrors these plates have a rubber pad preventing them from digging into the paint and body work. The holes are slotted for a universal fit and the hardware is THE name brand stainless fasteners so it will last a long time. The finish is the raw glass filled nylon and can be painted for a color matched appearance. LightTechs are nicer but for a track bike that just needs the mirror holes filled and bodywork held in place these are perfect.
