DescriptionThe whole story▼
Developed to meet the demands of full-throttle track use, the Brembo SSP 5.5 Brake Disc Kit brings genuine racing-derived braking technology to the BMW S1000RR K46 equipped with the HP4 forged wheel. Designed exclusively around the HP hub fitment, these floating SuperSport discs deliver the consistent, fade-resistant bite that separates a confident corner entry from a compromised one — lap after lap.
Key Features
- Floating SuperSport construction allows the friction ring to self-centre under extreme braking loads, maintaining consistent pad contact and preventing thermal distortion
- Engineered specifically for the HP4 forged wheel hub on the BMW S1000RR K46 (2009-2018) — a direct, precision fitment with no adaptation required
- Optimised compatibility with Brembo brake pads ensures the braking system operates as a matched unit, maximising feel and modulation
- 320 mm disc diameter paired with a 5.5 mm disc thickness — dimensions tuned for the aggressive braking demands of track riding and performance road use
- Built for high thermal and mechanical loads, delivering extended service life even under repeated, intensive braking events
Track-Bred Performance on the S1000RR
The SSP range sits at the heart of Brembo's SuperSport line — components developed in motorsport and then refined for the high-performance street and track segment. On a motorcycle as capable as the S1000RR K46, the braking system is a critical limiting factor. These discs address that directly: the floating carrier design reduces the transfer of heat into the wheel and caliper assembly, keeping brake fluid temperatures lower and preserving pedal feel through long, demanding sessions. The 34 mm friction ring width and precisely machined 80 mm bolt-hole axis geometry ensure even pad sweep across the full working surface.
Built Around the HP4 Forged Wheel
Standard S1000RR brake discs are not compatible with the HP4's forged wheel hub. This kit — part number 208973754 — was developed specifically to address that. The six-bolt interface with a 64 mm inner ring diameter mates directly to the HP4 forged wheel, making this the correct solution for any S1000RR K46 owner who has fitted or retained the HP4 wheel package. No modifications, no adaptors — just a clean, factory-correct installation with Brembo's race-proven technology at the centre.
