Of what the extra mounting tabs on the Seca 550 frame are for. All along I've suspected they weren't just for the optional luggage rack. Then I scored this great European (Yamaha of the Netherlands) XJ550 brochure off eBay and LOOKY THERE: a grab rail! WE didn't get a grab rail; just a "standing handle" on the left side, and a tab for an optional (or aftermarket) luggage rack. We got a dumbass across-the-seat strap instead. (Note the lack thereof on this bike.) OK, Eurozone XJBikes members, help me out. Find me one. It can be rusty as long as it's straight and solid, I'll get it replated. We didn't get a choice of color schemes either, just one for each model year. Or an oil cooler. Also, note the slight rearward difference in the rider footpeg position, resulting in a noticeably shorter rear brake lever. I THINK this is a 1982 model-year brochure; the "LIT" part number ends in "-82E." (82 Europe?) But I can't find a real date on it anywhere; so if somebody could confirm that as well, that would be great.
