The GSX-S1000/F has the same top-of-the-line radial-mount Brembo monobloc calipers as the GSX-R1000. The calipers each have four opposed 32mm pistons acting on a 310mm floating-mount disc for strong stopping power. An antilock braking system (ABS) helps the rider stay in directional control even during hard braking. It monitors the wheel speeds 50 times per wheel rotation and matches stopping power to the available traction. The ABS control unit has a compact, lightweight design that helps make the bike nimble.
