probably been said a few times now, but do check ALL your required documents, especially with french police being a bit more actively checking UK bikers.Try and take a copy of each too , as its your lifeline.I do think take a simple high vis vest just in case, and one of the breath test double packs....just saves any aggro.
If you forget an item of clothing it can be replaced , I even bought a phone charger for a new nokia phone in Italy in 06( so most things can be obtained...)...but without yer docs you is fecked !!
Pace yerself, dont get too carried away if you find a superb bit of road, enjoy the sheer experience rather than just trying to go as fast as possible.You can always turn round and ride it again ! ..which we did a couple of times on our first trip abroad.
Probably the biggest thing I learnt over the last 8 yrs of foreign touring is to relax and enjoy it , expect the unexpected, and try to laugh at any mishaps ! No matter how well you plan things, stuff can happen....
Hope you have a great time.... we is orf to slovenia on 6th July ! yippee!!
