I, for one, love the look of the "new" 750...I think (aside from the previously mentioned dohc look) they have been quite faithful to (their own) tradition of aesthetics with the new model. The refined look of the signal lights, etc, the engine side covers, pipes, muted colors, gauges and bars all bear a close resemblance to the former. I don't think it's intended to replace the old models, but rather pay tribute to it, and I could easily see how from a collector's standpoint this bike would be a necessary addition to the collection...
Anyway, I don't really know anything so take this as such...
