These were popular on FZ1OA. Fits nicely under the seat in front of tool kit on Gen 1. The bag is plenty big to hold a good T handle reamer and driver for the black gooey string thingies.
I went decades without ever getting a puncture and then in rapid succession had two, both with the wife on the back, which means there's no one to bring the truck. Got this set up and have repaired two other punctures on the road.
Probably been many advances in the last few years.
Oh and Happy Safe New Year
