TRW Fixed Brake Disc (MST508) — Replacement disc designed for road and touring. Made from stainless steel with a silver finish, this 300 mm diameter round rotor features a laser-cut silhouette for precise assembly and a distinctive visual identity. Its controlled roughness limits the risk of brake pad glazing and contributes to even wear, even under intensive use.

Check compatibility with your model (among common applications: several Harley-Davidson Touring/CVO models) and have the disc installed by a professional to ensure safe fitting and optimal braking.
