The article was about the GTL. No matter, aside from the addition of a trunk and a few mm difference in the handlebar and footpeg positions, the differences are minor. That is not my opinion. Every comp article, as well as the BMW forums say the same thing.
It's ok that we differ on this. It is mostly opinion for the most part, so there is no right or wrong. What matters is what buyers think on the sales floor. The two of us obviously place a different value on the various aspects of a bike.
No big deal. Just different opinions.
IMO...The GL1800 could be called a Sport Touring bike if compared to a HD Ultra or the old GL1500 but I wouldn't consider it one.
Point being...a bike can have strong performance and still not ne a sport touring bike.
Any bike with a non-detachable trunk and a passenger seat fit for a queen is not a sport - tourer to me.
PS...just a side note but the concept of "value" isn't of any relevance to me in of this discussion. I have a real sport touring bike in my garage and a Goldwing. I value them both and could go cross country on either. However, both are definitely different classes of bikes, do different things, and have different strengths and weaknesses.
Adding personal value to the conversation, here are my thoughts. I've owned a K1200LT and a previous GL1800 and I've ridden the K1600GTL a couple of times. As an honest comparison, I think the K1600GTL is a fine touring bike but the GL1800 was more comfortable for 2Up touring with my wife so we bought a replacement Wing instead of the K1600GTL.
