Toolkit for the BMW included Final Drive / Fuel pump Controller, Snap-On Tool Chest and £75,000 of BMW tools, for the Yamaha I go with:
1. Breakdown cover
2. Credit card
Never needed to use them in the last 15+ years of Jap bike ownership.
Puncture kit makes sense, I carry one, but more important is breakdown, my mate had a tyre fall apart in the Alps in 2011, the casing started coming through (iffy tyre) so the puncture kit was no help - and you cannot guarantee a puncture repair will work, still worth having a kit as it will save some hassle if it does work.
Now ask yourself what can you do roadside :question:
and
What would you do roadside :question:
On an RTW trip it may be you in the desert on your own, in Euroland your never far from help (a phone call - biggest issue is likely to be breaking down where your phone don't work - carry an extra pay as you go sim for another provider if your that worried, but even on remote Alpine passes someone will come along at some point before you starve.
In reality your not gonna start stripping your bike down at the roadside - and it is a Yamaha so should not need it.
With no chain to adjust I cannot think of anything to do, at home I carry no tools, on a tour just a few cable ties, pliers, cutters and a few Allen keys / Spanners / Screwdrivers in case something shakes loose.
