The floating-mounted Brembo 78B40894 brake disc from the Oro series offers maximum performance and quality for motorcycles and is designed to deliver consistent braking performance under high thermal and mechanical loads.

The stainless steel friction ring is connected to the inner carrier, made from CNC-machined and subsequently anodised aluminium, via drive pins. This construction allows the friction ring to move and expand slightly when exposed to heat without creating stress. This ensures improved temperature compensation and consistently smooth response, even under intensive use.

The brake disc design is engineered for high loads and ensures even power transmission, even during sporty riding. A specially tuned hole pattern supports heat dissipation and contributes to uniform temperature distribution. The combination of precisely manufactured CNC components as well as steel and aluminium ensures a long service life, reduces noise and minimises vibrations during braking.

• Maximum braking performance even under high loads
