I have a few bikes, the bigger one uses tubeless tires, flats are rare but need fixing on the side of the road or track when they happen.
Most tire repair kits are specifically made for motorcycles, they are car or truck version, and can be a little big or excessive, especially when space in your luggage is limited.
I'm always on the lookout for smaller and lighter solutions that do the same thing, that obviously someone has taken a little time to think about and design a better smaller solution.
This one by Lezyne is for bicycles but will work for motorcycles as well and is small and self contained
What do you think or use?
