Here's my tool pouch that I transfer between my RX3 and Honda NC700x.
Tool pouch from Christian Motorcycle Association. Adding to things already mentioned: zip ties, master link for chain emergencies, chain cleaning brush and lube, multitool, spoke wrench , spark plug socket wrench, adj. cresent wrench for axle nuts, feeler gages for setting valves, tire tube patch kit, air pump, appropriate fuse puller.
I put the longer tools in these tubes under the side cases held on with hose clamps.
