I wanted a motorcycle that was smaller and nimble. I fulfilled those requirements with the BMW G310R, however, I must tell you there is absolutely nowhere on the bike to stow anything. I see out on the streets, a lot of commuter riders wear a backpack. I didn't want to wear a backpack every time I went for a ride. The solution for me was a tank bag. The GIVI tank bag attaches to a ring around the gas cap and is very easy to snap on and clip off. The bag houses a GoPro camera and 3 batteries, cellphone with charging capabilities, a baseball cap, sunglasses and a small bottle of water. There is a little more room for some additional items if needed.
The next accessories I added was the GPS and battery wired in 2-port USB. The hub powers the GPS and the cellphone in the tank bag.
