Motorbikes aren't clones, they're not infaliable, every make or model can break down.
It's annoying when they have known faults, or weaknesses......but you look at any review of any bike that's been around a while and you'll find a 'look out for ...' on an issue with most of them.
I had a Honda 1300 Pan break down on a trip to Switzerland once...it was a 'it might get you home, or it might give up in 5 miles' scenario!.....I had to turn around and nurse it home, ruining my holiday!!
......that doesn't make all Pans crap bikes...merely I had mine break down!!!
I also took a Pan to Romania a few years ago when they were ravaged with heavy rain and floods, and all the roads were being washed away and it performed well beyond it's 'ability' and never missed a beat!...and that included off roading and crossing rivers on it at times!!!
My GSA's have been to Albania, Ukraine, Bosnia, Serbia, Montenegro, Macedonia...etc etc

.......and they've performed brilliantly.
I may have been lucky.....but if they do breakdown at least your not far from a BMW (car) dealer, and they'll get you the parts you need....not like the Triumph rider I met in Macedonia who had been waiting weeks for his parts.
It's easy to get paranoid about breaking down....but fear is a waster of opportunity.
