Well, it'll be interesting to see how the two actually stack up in the real world. Speaking for myself I can say that the new Sprint ST appeals greatly. I could never get excited about the current Sprint because of the lame (IMHO) styling and the cruddy OEM suspension. The new Sprint addresses my concerns and I can finally get excited about it.
The K1200S is appealing too, but I like to save money and frankly, based upon my own extensive experience and the experience my friends, I just don't trust the BMW brand as much as Triumph. Been there, done that, replaced the self-destructing Beemer tranny
The clincher is that I have a great local Triumph dealer and I like doing business with him.
