I don't think it will be a significant cost regardless, but as the previous poster said, Yamaha did ship every S10 with three lock barrels coded to the ignition key that are designed to fit in the factory accessory luggage. Now some dealers may have threw them in the trash when they delivered a bike w/o luggage and some owners may have lost them. But they were supposed to come with every bike.
Priced reasonably, you should have no trouble selling your luggage - you might get a little more money on Ebay, but you could run an ad here. (This forum does tend to be US-centric and shipping costs are going to be significant. I suspect the market in Europe for used luggage is softer because if the 1st edition bikes having the luggage bundled with the bike, whether it was desired or not.) Despite the complaints, there are many who prefer the factory system.
