We know all the subframes are new because the fairings, mirror mounts, tail piece, passenger footpeg brackets, etc., are new. The forks are new but the bearings and lower triple tree might be the same (the upper triple tree being changed for the new handlebar mounts). The tank mounts higher, the side covers are different and the swingarm is longerand the venting through the steering head/cockipit area is increases, so it is possible that the frames are completely different.
vectervp1 could be onto something...it could be as simple as a powdercoat change. Until someone disassembles one and compares, we won't know for sure (Except for the Benevolent Dictator, the Keeper of All Knowledge.). Are you volunteering?
