Timaloy: I agree with much of your thoughts, but having owned more than a few BMWs over the past 30 odd years I think that perhaps you have been a little unlucky with your BMW woes. or perhaps I have just been lucky.
Having said that, I have recently transferred my affections to Honda, first with the Integra 700cc DCT, joined by a manual Crosstourer, which, whilst is still new to me, has greatly impressed me, particularly that V4 engine, so much so that I'm thinking about changing it for the DCT version instead. All I really need to resolve is panniers and I'm hoping that touratech or preferably MM will come up with some frames.
