Hi All! Yes its true! I just got a set of Metzeler Roadtec 01. Got the OEM sizes front and rear (190/50). On initial ride it seemed the bike is geared longer. So, l tried to verify the tire specs from manufacturer--all responded except Metzeler. The D214 is a bit of a odd ball. The height numbers from Dunlop Rep were 24.56 inches (D214) vs. 25.03 inches (Q3, which is what the Rep said is their recommended replacement) or 24.72 inches (Road Smart 2) (side note, a Road Smart 3 is being released next year). Anyway, the bike has a very nice stability at lean and doesn't have the "power steering" turn in characteristic I disliked about Michelin Pilot Powers. Haven't had a chance to hit the twisties yet, and its too early to see if they get the mileage I hear guys getting from the Michelin Pilot Powers or Pilot Roads. And they look way cool .
