These were the last years of the Falco, and the bike was essentially unchanged from the 2002-2003 version. It still had the detuned Mille V-twin, the aluminium twin-spar frame and the half-faired sports-touring layout. Sales never met Aprilia's hopes, and the model was dropped without a direct successor. That makes these late bikes a fairly rare used buy.
