2003 Ducati ST4s ABS, 2003 Ducati ST4S ABS - This is the first Ducati to include an Anti-lock Braking System (ABS), adding a new level of safety to the Sport Touring family. The state-of-the-art ABS system engineered by Ducati delivers unprecedented performance in comparison to the systems currently found in the industry. The purpose of the ABS system is to prevent the wheels from locking-up during emergency braking and low traction situations, one of the main causes of falling on a motorcycle. The ABS does not reduce the braking distance with respect to that obtainable by perfect braking by an expert, but minimizes the distance according to the friction coefficient and, so, the asphalt's maximum grip. Even the most expert rider would not be able to attain this type of performance in all conditions . The system installed on the Ducati ST4s is produced by Bosch and has had its settings developed by Brembo in collaboration with Ducati . An important goal for Ducati in introducing the ABS system was to ensure that the Ducati system maintained the same feeling as a traditional system . Reacting to the sports riding priorities of the ST4 customer, the Ducati system gives optimum sports braking feel and feedback , as opposed to the spongy feeling typical of other ABS systems for motorcycles. This grey ST4S ABS is in good shape. Bike does have minor scratches on it, is all stock, has a tinted windshield and a Ducati accessories dual headlight kit.
