I guess the brakes will hold up very easily during street use even at speeds of up to 300 kph. Whenever i see a video of blokes going 300+ on the long stretch at Spa with these ‘roadbikes’ slamming the brakes decelerating to 80 kph over and over again .... .
Offcourse they will wear out pretty quickly but i guess you can do several track days with a set of brake pads.
