The Moto-Master HALO Series sets a new standard in aftermarket circular-round design brake rotors. Its premium quality stainless steel outer ring allows for high performance braking while at the same time extremely durable. Exact size and positioning of the venting holes ensures equal heat dispersion under high thermal stress while the brake pad contact surface is cleaned evenly. The laser cut and precision grinded outer ring is fixed to a billet CNC machined aircraft aluminium carrier which is black anodized and laser marked. Newly designed lightweight stainless steel floaters complete the package. Halo Road Disc is also available in Halo Racing version in 5.5mm thickness. For best performance we recommend using Moto-Master brake pads. All Moto-Master Discs are T-V approved.Brake Rotor Halo RearOuter diameters 245.0 mmInner diameter 115.0 mmThickness 4.0 mmNumber of holes 6Hole diameter 8.5 mmPitch 133.0 mmType Fixed DiscTurning direction OmnidirectionalSpeedometer prepared No
