Product Information

Full details

The EBC X-Series Floating Motorcycle Brake Disc is designed for performance-minded riders looking for a lightweight, reliable upgrade over OEM components. Its primary benefit is the patented square drive button system which prevents warping and reduces unsprung weight for better handling. While it offers superior thermal management and friction, prospective buyers should note that these discs are sold individually and require careful verification of fitment for their specific motorcycle model to ensure direct replacement compatibility.

FAQs

Are these discs sold as a pair?

No, the EBC X-Series brake discs are sold individually.

What makes the X-Series different from standard rotors?

The X-Series features a patented square drive button system and a floating design, which prevents warping and provides better heat management than standard fixed or semi-floating rotors.

Do I need new brake pads with this disc?

It is highly recommended to install new brake pads whenever you replace your brake discs to ensure proper seating and optimal braking performance.

Can this disc be used for racing?

Yes, the high-grade stainless steel and lightweight design make them suitable for high-performance street and light track use.

How do I ensure this fits my bike?

Verify the MPN MD1171X against your motorcycle's model, year, and specific trim level requirements in your service manual or the EBC fitment database.

Is the floating mechanism supposed to move?

Yes, the full-floating design is intended to allow for slight lateral movement to ensure the disc remains centered between the brake pads.

Troubleshooting

Brake lever feels spongy after installation

This is typically caused by air in the lines, not the disc itself. Perform a thorough brake fluid bleed.

Clicking or rattling sound from the rotor

The full-floating design naturally allows for some movement; however, ensure all mounting bolts are torqued correctly and check that no foreign debris is stuck in the drive buttons.

Braking performance feels inconsistent during break-in

New rotors require a bedding-in period. Ensure you are using new brake pads with the new rotor and follow a standard cycle of gentle braking to seat the materials.

Pros and Cons

Pros

  • Significant reduction in unsprung weight
  • Advanced square drive system prevents disc warping
  • High-grade stainless steel construction ensures longevity
  • Consistent and reliable braking performance under heat
  • Reduces harmonic vibrations during deceleration

Cons

  • Sold individually rather than in pairs
  • Requires precise verification of OEM specifications
  • Premium performance comes at a higher complexity level than budget rotors

Setup, Compatibility & Care

Before installation, use a digital caliper to verify your current OEM disc dimensions to ensure the MD1171X is a direct replacement. Ensure your mounting hardware is clean and debris-free. During installation, it is critical to torque all mounting bolts to the manufacturer's specified values. To ensure proper break-in, avoid aggressive, emergency-style braking for the first 100 miles to allow the new rotor surface to 'bed-in' with your brake pads. Periodically clean the surface with a dedicated brake cleaner and inspect the drive buttons for any buildup of road grime or brake dust to ensure they remain free-floating.
