At some stage, you will be required to use your tools. For me, it was nearly every other day. In my tool box, I had everything I needed to fix most of the things you encounter each day. Each morning before my ride I would do a simple check over my whole bike, in the end, it just became routine.
For my tires, I had the tools I needed to change a tire, to inflate my tires (mini compressor), to repair a hole or puncture.
I also had a custom designed toolkit for my bike so that I could fix any loose nuts and bolts (part of my daily check) and even though I did this, I did lose a couple along the way.
I also carried WD40, Chain Lube, Brake Fluid, Clutch Fluid and one liter of engine oil and coolant.
