The tourpak is solid and you don't even know it's back there. I like the size of the Razor bag. I can easily throw my leather jacket, tee shirt, gloves,sun screen, spare shades, bug cleaner and a couple rags. I forgot to mention that I did buy an aftermarket lock assembly with two key positions. I wanted to be able to pull the key out in the locked and unlocked positions. The lock that came with the tourpak had one position "locked" that the key could be removed. It turned into a major pain. So I replaced with a high quality aftermarket lock.
