Safety Lock Wire
Typically, they look like this when they are sold

... but you don't need to buy that tool (at least, for now).
Just get the wire, cut and roll into convenient size, keep it under seat storage.
When you, as a motorcyclist, get stranded on the road, the reasons are usually ...
1) You run out of gas
2) The parts getting loose and have fallen off (or dangling)
3) Flat tire
4) Battery is dead
About the gas, there's no easy solution for us Monster riders.
Back then when I was riding 2-storke that run on pre-mix, I HAD to carry extra gas (pre-mixed).
But, carrying extra fuel bottle on Monster every single time you go out for a ride is ... pretty unrealistic.
You just have to train yourself, to get a gas as soon as you see low fuel warning light.
2)The parts getting loose and falling off or dangling ...
Assorted zip-ties take care of many of this type of problem.
However, when something that's generates a lot of heat (such as exhaust), you need wires.
It has happened when I was in a group ride (which I no longer do).
If someone's bike breaks down, you have to fix it, otherwise, everyone gets stuck there.
Of course, you need a pair of pliers, but I will talk about it later.
4)Flat tire
I carry "Stop and Go tire plug kit".
They don't sell the version I have anymore.
This one is the closest. And it will come with CO2 cartridges.
