Me and my sister did a camping trip by motorcycle a few years back, starting off in Norfolk, England then across to Holland by ferry and we rode through Belgium, Germany, Luxemburg, France, Leichtenstien, Switzerland, Austria and Italy, then came back mostly through France.
I did all the 'piloting' as my sis didn't have a licence, and it was quite tiring as we did all that in one week. But the bike was well behaved, even loaded up, I raced a Ferrari in Italy, until sis got panicky and hit me
It was an excellent trip, the only downside was the pre-Euro currency changes - we had pockets full of coins - German Marks, French Francs, Austrian Schillings, Italian Lira etc. etc. we must have done an exchange nearly every day
Two things stand out even now:
The Swiss have the best camp sites in the World 8)
Mountain passes may look nice, but hairpin bends are hellish to get round on a bike....
Oh and the bike? a Suzuki GSX600f - RIP my friend - burnt to death by an obnoxious scumbag, but that's another story...
