If you can find the old Craig Vetter triangular saddlebags and trunk, they were Hondaline accessories at on time, and they work well. But, they are permanently mounted. You would have to fabricate your own mounts custom for your bike, but they offer locking lids, and security as well as capacity.
For soft bags, get a tank bag and a set of cordura nylon bags. RKA in Shasta, Ca makes a great set of saddlebags that are easily expanded with just a zipper. About $300 for them in custom colors, less with generic colors. I got my wife a set for her 2015 Can Am Spyder RSS, and she Loves them. If you mount a sissy bar/backrest, there are bags that can strap to that, as well.
