Check out the BMWMOA BMW motorcycle owners association web site. You'll find all the dirt there. Note that every once in a while someone posts about an ST problem here. The issues are sparce and different. Lots of owners have the same recurring problems with the BMW genere. Some models more so than others.

Hi Robert. You should take your rose tinted glasses off
Anyone researching the ST1300 here without asking questions would go straight to the technical or issues forums and see one word more than any other... Heat! Closely followed by instability or wobble concerns, pulling to the left, hot pockets, screen buffeting, uncomfortable seats etc etc. In other words recurring, common, issues and concerns.
I'll admit that the ST doesn't appear to have any inherent catastrophic mechanical failures but you have to put the BMW ones into context of the volume of bikes sold amongst many others. In addition, the vast majority of K bike related issues you read about on the BMW forums are for the early build bikes and from 2006/2007 most, if not all, have been thoroughly ironed out.
I'm not trying to say that one is better than the other and in fact it does appear that of late, BMW have released many models without sufficient testing and build quality whereas Honda are renowned for mechanical reliability.
People generally, apart from a minority of friends, tend to resort to posting on forums when they have a problem and want some help and advice. My point is that anyone using them to research any bike, including the ST1300, is only going to get a one sided view unless they ask. Try it... go and post on one of the BMW boards and say you're thinking of getting a K1200S. Then, just as here, you'll hear from many more than satisfied owners who've had no issues at all and covered huge mileages.
The Honda ST1300 is a great bike for some people, no doubt about it, but so are many BMW's.
Still looking forward immensely to getting mine
Regards,
