The brake callipers of the S 1000 RR (2025 model year) are cooled directly by the air flow in the M brake duct front-wheel cover. This has the following advantages for you as a rider:
- More braking power
- More stable braking point when used on racetracks
- The fork legs are better protected against stone chips
M brake ducts are also used on the BMW M 1000 RR; read more here.
