Did you even read the quote from MCN?
Uh, about four times, once when I got the issue and noted what they said, second when Bones posted several weeks ago, and I remembered it from the first time, and in this thread, two more times.
Funny, it just goes to show you how people can read the same text and get two different reads on it. I read it thusly: they did not think the lighting worked as advertised in that the adaptive lighting feature SWIVELING into turns wasn't that dramatic/useful/working as advertised. In no part did I read that under normal riding conditions that the lighting wasn't adequate... and in my estimation, from one who has ridden BMW's with the Xeon lighting it is, pardon the pun, the difference is between night and day. If I read Dave Searle's gripe right, the usefulness of the system is only apparent at high speeds and in level road conditions... it does not suck as you put it from a lighting standpoint as compared to other bikes, it just does not meet the expectations of the advancements BMW has placed on it in regards to moving into a turn. So, it appears that BMW has some refining to do.
And as to your other points, if you read my posts here in the past, you will see that I am not a BMW apologist when it comes to their issues, but you bring them up to justify that their engineering prowess in this one area is suspect. I applaud their innovation in thinking out of the box... and that is what you get for leading at times... arrows thrown at you. BTW, I happen to LOVE my servo-assisted brakes, both on my 1150RT and now 06 1200RT. The only reason for BMW going away from this is not any failure rate on the brakes but rather the motorcycling community not liking the "feel i.e.-sensitivity" of their performance, you ride with them day in and day out, you get used to them as I did... these comments usually are the same folks who rather hated the much more ergonomic BMW turn signals that BMW had up until 2010. I just chalk it up to different strokes for different folks. Final Drive Failures are there, I give you that... I would however like to note that both would be in the minority of bikes and also in my 120,000 miles on my three BMWs, not a problem between them. Duolever suspension is fine for me... as I have stated earlier, I have ridden both the 1200 and 1300GTs and other than a slight vagueness to the front end compared to my Telelever on my RT, I didn't experience any harshness on the front end.
So, that is my take on your take of my take... make sense?
Peace out.
