I build tool kits custom for each bike. Standard OEM tool kits are pretty much a joke and I replace with high quality tools and test them out
working on the bike in the garage before departure. My tool kits are constantly evolving as I get better ideas to solve problems and eliminate pieces I do not need. Every new bike presents new challenges. And every trip is different in it's requirements. Don't bring tools to re-build your bike on the side of the road. Not going to happen. But DO be prepared to deal with minor issues, crash damage ... and of course ... lending bits and pieces to riding companions on BMW's.
The kits pictured below are old and have changed several times since I put them together. But the travel kit is pretty good and has a few things of note:
Valve stem tool ... must for tube type tires
QUIK Aluminum or QUIK Steel ... amazing
Two part JB Epoxy weld
Stick Magnet ... very handy
NOT pictured: Head Lamp ... another must have. Make flashlights obsolete!
Also Not Pictured and very important: Nut & Bolt kit (a nice collection of OEM sized nuts, bolts, washers, springs, doodads)
Spare levers ... even with bark busters it is possible to break a lever. Spares are nice.
Fork Seals. Small, easy to pack. But do you know how to install them?
Fresh Glue to patch tubes, patches
VOM meter, fuses, Crimp type connectors, misc. elec.
Only bring Allen keys that fit your bike. No extras.
ratcheting combo wrenches ... nice 8mm, 10mm, 12mm, 13mm ?? (make sure you're bike uses 13mm) 14mm, 17mm, 19mm
Tire tools for removing axles front and rear
Tire Irons (not shown ... but I carry three)

Cent. America Tool kit for DR650

Tubeless Kit with mini compressor, string plugs, BMW type plugs, CO-2 set up, hand pump (not shown)
