I keep extra tools in this small tool roll that conveniently fits under my motorcycle's seat.
My BMW famously came with an under-seat toolkit that can mostly fix any problems from minor to pretty large. It is greatly aided by a few extra bits and pieces that will not fit in the OG tool roll. So I got this one.
It is cheap. It stores tools. It fits. What else could I want?
I will spare you a picture of my motorcycle's under-seat storage. It is truly the least interesting part of my bike.
