Just got a 2001 R, seems very lightly used with just a few hundred miles on it. The swingarm and axle do not seem to be bent at all. I was inspecting the rear caliper and noticed a straight crease, or so it appears, beginning at the caliper guide rail on the right inside part of the swingarm for a few inches. Noticed two similar parallel ones on the left swingarm (on the inside as well) that are several inches long. I can't get pics up yet. Is this a normal remnant of the manufacturing process or something to be concerned about??
