I like the new ST's. Not a huge departure, but then it seems that Ducati has decided that Sport Tourers aren't for the stylistically adventurous, so an evolutionary, almost Japanese approach shouldn't come as a surprise, I guess.
I think Terblanche is a hell of a designer. The heat he's taking is inevitable, I suppose, and kind of reminiscent of the crap that the new design head at BMW autos has been taking. Guess it ain't easy being a design visionary working for a company with a design history like Ducati (or BMW).
I like the new(ish) SuperSports, the 999 and, especially, the Multistrada. Not nuts on the front ends, but the rest of them are just outstanding, IMO. But it's the fact that the latter two are such practical steps forward that really sets Terblanche apart. No, he may not be the stylist that Massimo is/was, but he's designing better bikes, IMO.
In the long run, I think that's what will count.
