I've been working on building a rack and case system since before I even got the bike. I finally finished putting it all together today. The top rack was put together on a template, but the side racks had to be welded together with brackets attached directly to the bike because of the complexity of the geometry (precautions were taken to protect the bike during welding).
The cases attach to the racks using 3 compact machined aluminium brackets and matching inserts that incorporate a lock. Inserts attach to the cases using a steel plate with extra anchor points for nylon straps. All cases are interchangeable. The large cases are Nanuk 940 (36 litres each) and I have a 4th smaller Nanuk 915 top case (13 litres). Nanuk cases are similar to Pelicans, but I find the latches much easier to operate and the cases more aesthetic.
I did a small test ride this afternoon and nothing budged or made a noise so I'm very happy with the results. The cases are positioned to clear the angle at which the footpegs would touch the ground while staying as close as possible to the axis of the wheel and low to the ground for stability and balance. Wind drag doesn't seem to be a problem either.
I will have the aluminium brackets anodized black later on. Next up on my To-do list is a set of crash bars. I may also heat form the top of one of the larger cases to be able to fit my helmet inside.
Thanks for the compliments. I picked white for visibility, but they're also available in black, grey, green, etc. I'll probably stick some reflective tape on the sides. I would have liked to paint something and apply retro-reflective glass beads, but the cases are Polypropylene (or Polyethylene, can't remembre) so paint won't stick very well.
