After spending hours looking at all the various top cases, I couldn't get away from thinking the Emgo Trunk just looked right. Not too adventure, not too Buck Rogers. At $67.45 shipped on eBay, it's inexpensive.
My XL Arai Corsair fits fine. The quality seems good. I've ridden about 250 miles with it and it hasn't come lose or caused any problems. No rain experience but it looks like it should seal fine.
I had read that it doesn't fit the V-Strom without drilling but I found that not to be the case with my 2013 650.
I upgraded with lock nuts and added some fuel line "scratch protectors". Also, painted the brackets black.
I cuts notches in the side of the bracket that goes towards the front of the bike to enable sliding a 7/16" open end wrench between the top of the tail light and the bottom of the rack while tightening using a screwdriver from the top.
The nuts clear the top of the tail light - just barely. No scratches.
The fasteners seem to only fit in the 4 holes seen here unless you want to get out the drill.
This is the first in a line of racing luggage being developed by Yoshimura for the track. (R&R'ed the original Emgo sticker with this one.)
Placement is fairly limited front to back but should give a rear passenger enough room.
