I own a 2017 Harley-Davidson 883 Iron Sportster. I do not have the ABS brake system. Is there any way to improve on the brakes? They are not glazed, and I only have about 4000 miles on the bike. Can I upgrade the disc and pads? Brake pedal seems firm, it just doesn´t stop as fast as I would like. Master cylinder up-grade, or fluid up-grade? Braided brake lines? Help !
