I am currently in South Africa after travelling from the UK along the west coast of Africa. I brought a new F800GS Adventure at the end of June and left by the end of August with 3k miles. I now have 21k miles and the issues i've had are a puncture, headlamp bulb, left hand heated grip, head bearings and breakages from the bike ending up on it's side. The heated grip and bearings were replaced in South Africa under warranty.
For spares, i brought a length of wire, replacement inner tubes, two fuel filters and an air filter. The K&N air filter was advertised as fitting, did not fit on my F800 so i gave it away. I gave one of the fuel filters to a friend who needed to service their R1200 motorcycle so i have one for a service if i can't find a dealer.
For tools, my tool kit which contained Torx drivers for the bike, a couple of spanners to adjust the chain, a multi-meter, some patches, tyre leavers and a compressor. I fitted a scottoiler to help extend the life of the chain - which has worked for me on other motorcycles.
I went for the minimal approach - any spares i brought would not be the right ones and weigh me down unnecessarily. If there was something i needed that i couldn't sort out locally, i'd stop somewhere and get it shipped.
As long as your consumables are newish (break pads, chain, tyres), there should be very little you need for many miles of easy touring. If you are harder on your bike, your experience may vary...
