Brembo Serie Oro Fixed Rear Brake Rotor 68B40775 for Honda, TM, and Motorcycle Applications

Brembo Serie Oro brake discs are fully interchangeable with an Original Equipment brake disc. They consist of the stainless steel braking band connected by means of drive pawls to the hub made of CNC-machined and anodised aluminium alloy. The vast experience of Brembo was used to define the most correct geometries, tolerances and dimensions.  Resulting from a specific study of machining tolerances, the special conformation of Brembo discs allows braking torque to be transmitted more effectively while offering better resistance to thermal and mechanical stress. The Serie Oro was the range with which Brembo entered the racing world in the mid-1970s, quickly becoming the industry benchmark for discs.  Available in fixed or floating rotors.  

The Brembo Serie Oro fixed rear brake rotor is engineered as a direct replacement for an Original Equipment brake disc. Part number 68B40775 combines Brembo’s established braking technology with precise manufacturing for dependable performance on the street or track. The stainless steel braking band is connected to a CNC-machined and anodized aluminum alloy hub, creating a durable rotor assembly designed to manage braking forces and repeated heat cycles.

Brembo developed the Serie Oro range using carefully defined geometries, machining tolerances, and material specifications. This design helps transmit braking torque efficiently while improving resistance to thermal and mechanical stress. The fixed-rotor configuration provides a straightforward replacement solution for compatible applications and is suited to riders seeking consistent braking response with Brembo quality.

This rear rotor fits select 2008 TM MX 300 models; 2010 Honda SH150I models; and 1991–1997 and 1999 Honda CB250 Nighthawk models. Confirm the motorcycle year, model, mounting pattern, and original-equipment specifications before installation. Expanded fitment information may be available through WPS Orders.
