Description
GBrakes 12.5" Front Brake Rotor – Spoke Mount
Upgrade your Harley-Davidson’s front braking performance with the GBrakes 12.5" Front Brake Rotor. Engineered for riders who demand precise control, heat management, and consistent stopping power, this oversized rotor provides improved braking surface area and cooling performance compared to stock rotors.
Constructed from high-carbon 420 stainless steel, each rotor is laser-cut for accuracy, double-disc ground for perfect flatness, and heat-treated for durability. The solid-mount, one-piece design ensures direct bolt-on installation with the factory hub pattern — no modifications required.
Whether you’re pushing a performance bagger, cruising long miles, or commuting daily, the GBrakes Wave® rotor gives you smoother, fade-free braking and long-term reliability.
