I think I know what you mean, thought that was already moot since I changed from a road bike convertion to a track bike, which felt more manoeuvrable due to the fact that it's an actual track bike.
But what makes the track frame more manoeuvrable is exactly that, it (usually )has a shorter top tube, and shorter wheelbase than its road counterpart of the same size.
