One 1500mile trip to France over 4 days, two GS12, one R12, almost 5k miles, dissapointingly no FPC failures despite us being horrified from other people's stories and carrying the spares and comprehensive toolkits.
Apart from mine listed in the thread above, there were my mates 6k mile 1200R and the third guy's 05 GS with 35k km. At that mileage, apart from brakes and tyres he hasn't had a significant component fail at all.
