I carry a can of Fix-a-flat in a plastic bag under the passenger seat so it will not roll around, I also have a MC rope plug kit with 3 CO2 cartridges in the rear compatment with our rain suits and have AAA with motorcycle coverage!
Simple leaks can be repaired on the road and fixed later when I find a tire dealer!
Bigger prolems....... I can call AAA for a tow!
With no spare, and no lug wrench, that is about the best I can do!
