I have been studying this thread with interest, as it is the first time I've come across a suggested tool kit list for the Tenere. (Loads of stuff on the net, and even off the shelf tool kits for BMW's - perhaps they break down more often ;-))

This is what I've assembled so far, from my studies, (and a complete lack of mechanical knowledge) with the aim of having everything needed for a long trip, far too much stuff just for a trip down the shops.

No spares/consumables yet on the list, maybe that would be worth starting as a seperate thread? Anything I've missed, or don't need? I must learn how to post pictures
