Product Information

Full details

The EBC MD2123 Fixed Brake Disc is designed for motorcycle enthusiasts and mechanics looking to maintain reliable stopping power through a precision-engineered replacement component. Providing superior stability and consistent braking performance, this disc is an ideal fit for compatible models requiring a 220mm outer diameter setup. Prospective users should note that as a fixed-style rotor, it is specifically intended for applications where a floating design is not required, and exact bolt pattern verification is essential before installation.

FAQs

What is the outer diameter of the EBC MD2123?

The outer diameter of this brake disc is 220mm.

How many mounting bolts does this disc use?

The MD2123 utilizes a three-bolt fixing pattern.

Can I use this on a bike that currently uses floating rotors?

It is not recommended to switch from a floating to a fixed rotor unless the motorcycle manufacturer specifically approves both configurations for that model.

What is the thickness of the disc?

The disc measures 4.5mm in thickness.

Does this disc come with mounting bolts?

No, the mounting bolts are generally sold separately or reused from the original setup if they meet safety requirements.

Troubleshooting

Brake judder or pulsation felt at the lever

Check the disc for lateral run-out using a dial indicator or ensure the hub mating surface is perfectly clean.

Squealing noises during braking

Ensure the brake pads are seated correctly and consider using a thin layer of brake quiet lubricant on the back of the pads.

Pros and Cons

Pros

  • High-grade steel construction ensures longevity
  • Precision dimensions guarantee a perfect fit
  • Fixed design reduces mechanical complexity
  • Provides reliable and predictable braking feedback

Cons

  • Not suitable for motorcycles requiring floating rotors
  • Requires professional installation for safety assurance
  • Specific to three-bolt mounting configurations only

Setup, Compatibility & Care

Before beginning installation, verify that your motorcycle hub matches the 125mm fixing hole spacing and 8.5mm bolt diameter specifications. Ensure the mating surface of the wheel hub is completely clean and free of rust or debris, as any uneven buildup will cause lateral run-out. Always use a torque wrench to tighten the three mounting bolts to the manufacturer’s specified tension. To care for your disc, avoid the use of harsh industrial cleaners; instead, wipe the surface with a dedicated brake cleaner. When installing new discs, it is strongly recommended to pair them with a fresh set of compatible brake pads to ensure even bedding-in and to prevent premature scoring of the new rotor surface.
