Galfer Rear Brake Rotor for Yamaha Motorcycles (DF451W)

Upgrade your motorcycle’s braking performance with the Galfer DF451W Rear Brake Rotor, engineered for riders who demand consistent feel and dependable control. Preferred by many top AMA Supercross teams, this rear rotor is manufactured in Spain using Galfer’s unique laser-cut high-carbon 420 stainless steel and 8-composite construction. The material combination delivers durable performance for demanding street, track, and off-road riding applications.
The Galfer DF451W features precision laser cutting and double-disc parallel grinding to help ensure excellent flatness and smooth, predictable brake response. Its design allows the rotor to cool as it rotates, helping reduce brake operating temperatures during repeated braking and high-load riding. The result is reliable stopping performance with a controlled feel at the lever or pedal.
This standard-size rear rotor is designed as a direct replacement for compatible Yamaha applications and installs without additional parts. Confirm motorcycle fitment before ordering, as compatibility may vary by model and year. Galfer also offers oversized 10.6-inch rotors for select models; oversized applications require a separate brake caliper relocation bracket, which is not included with the rotor. The Galfer DF451W combines race-inspired design, precise manufacturing, and practical direct-replacement installation for confident braking performance.
