Made it as far as Gibraltar on one of my trips out, via France, Spain, Luxembourg, and Portugal. Cost me a clutch when I got back to the UK and a couple or so pints of oil to keep the engine toped up while traveling.
Traveling wise the worst bit was see a petrol station closed and was desperate for fuel and ran out as I pulled on the slip road at the next petrol station.
Got to Gib and the worst of it, got ripped off on the accommodation prices, and its as mad as driving in Birmingham, apart from plenty of sun shine.
There was no numb bum, the luxury in those days of a BMW R80 RT great comfortable bike to ride, apart from the heat given off by the cylinders straight onto ones feet.
