Just picked up a used 06 Buell XB9R

Oh that makes sense. Does it make a difference that these are coming off of a XB9SX? Because I am fairly certain that the lettering is different from that of your bike, thrstrmech since your lettering is gray and this is black.

A Google search shows some models with black and some with gray lettering.

the link you posted states the airbox came off an '03 9s... the 9SX didn't have yellow plastics, maybe owner changed the decals, but doubt it...ask him for close up pics if possible, either way no big deal
