My Wilier GT Ex Large (about 59cm) weighs 18.6 with two cages and 105 pedals, full ultegra group. My Motobecane Immortal Spirit dura ace 7800 (smooth too) weighs 18.3 in a 59 Cm same 105 pedals. I ride basically the same on either bike but they do fit different given the geometry. The Moto is twitchier on high speed descends, the Wilier feels more stable. Maybe a bit more get up and go from a dead stop on the Moto. I could upgrade the wheels on the Wilier from Shimano RS30 and build a set of velocity's and lose a pound I bet. Probably would not go a bit faster.
