The capacity to carry anything on the BCR is zero. Well, actually, the area under the rear seat cowl is adequate for the few items I want to carry, but it is very inconvenient as you need a coin in two places to take it off. Not convenient at the toll plaza ;-) However, you don't want saddle bags on this bike, and the tail packs for sport bikes have bungees or other soft luggage options that are overkill. That leaves a tank bag of some kind. I decided to simply get another gas cap ring for my SW-Motech bag used on the GS. It is sleek, big enough for the basics, and low cost. We have a winner!
