Hello,
I was steered here from another BMW K site.
I traded a Buell S1 for this K100, rode it a few times and am thinking of selling it to buy another Triumph Sprint.
What I can tell you is that it runs fine, starts right up and it needs fresh tires, steel braided brake lines, Ferodo pads, indicator lights and a general going over to get it ready for the riding season.
The bike is in good shape but it's not perfect. Fox shock, San Jose BMW fork brace, Luftmesiter fairing and I believe that's it as far as aftermarket items go.
Comes with the original manuals, tool kit, spare key and is located in Central PA (between Harrisburg and Baltimore).
