High quality, factory supplied lower cowl component for the fine and iconic Fireblade (and similar models) sports motorcycle it suits.
Don't spoil your machine with cheaper and inferior pattern copies that will last no time at all before cracking and degrading (assuming they did not start to crack when fitting them). Panels fit correctly and look absolutely right, and bracketry lines up with the fastener holes precisely. New fasteners would also finish off the installation very nicely.
