I am looking to purchase a 620 ss and noticed that the bike has holes on each side of the full fairing for use with sliders. Now, my question is this. Could this have been a factory option/installation or is it more likely that the owner bored the holes though the fairing? I ask this question because the holes looked finished. They are rounded smooth and painted. Looks like a professional job. I would imagine that if someone were capable of boring holes in the fairing they would not go through the trouble to finish them, unless of course they are anal- retentive or something. The holes even have a black plastic grommet looking piece. What are you thoughts on this? thanks for you help.
