Aprilia RS660 Jet Prime ABS DeleteJETPRIME ABS Eliminator for Aprilia RS TUONO TUAREG 660. For racing use, the operation of the original ABS is not congenial as it extends the braking too much, especially in conditions of imperfect grip. Our device allows you to eliminate the ABS modulator from the bike, saving about 1kg of weight. No error lights will be lit on the dashboard and all normal functions will function properly.
