I have both a RKA tankbag and rear rack bag. If I had to do the purchase again, I would look elsewhere. RKA makes decent luggage, USA made for the patriot in you and they can do custom colors like nobody else can. The color thing was the compelling reason for me, but otherwise RKA is just average in quality of materials (cordura seems lightweight to me, zippers are not heavy duty) and overpriced. In fairness, quality of construction was tops. But rain covers are extra and without them, expect to spend more money on pricey 303 Protectant (RKA says so). They seem very customer responsive (the owner himself may likely answer) as well. But, overall the bags honestly left me feeling a little disappointed in value. Do not even think about asking them to do a custom change to the design of their bags (other than colors), what you see is what they offer. So,YMMV with RKA, but I saw a Cortech bag in the moto store just today with thick, bombproof looks and huge zippers with large rubber pulls. Yeah, the color choices were black and....black, but I would trade the RKA for the Cortech in a heartbeat.
