Brembo Serie Oro Rear Fixed Brake Rotor 68B40746 for Kawasaki KLX300R

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 rear fixed brake rotor is designed as a direct replacement for the original equipment brake disc on select Kawasaki KLX300R models. Manufacturer part number 68B40746 delivers reliable fitment and consistent braking performance for riders who demand dependable control in off-road conditions. This rotor is engineered for the rear braking system and is compatible with 1997–2006 Kawasaki KLX300R motorcycles.

Built from a stainless steel braking band and connected to a CNC-machined, anodized aluminum-alloy hub, the Brembo Serie Oro rotor combines durable construction with precise manufacturing. Brembo applies carefully developed geometries and machining tolerances to promote effective braking-torque transfer while improving resistance to thermal and mechanical stress. The fixed-rotor design provides a straightforward replacement solution for the original equipment component.

Serie Oro represents the product range that established Brembo’s presence in racing during the mid-1970s and helped set a benchmark for performance brake discs. This rear rotor is manufactured for accurate installation and dependable operation when paired with compatible factory braking components. Always confirm motorcycle year, model, and brake-system configuration before installation. Expanded fitment information may be available through WPS Orders.
