EB7 & EB9 BRAKES FAQ

10 April 2026

What’s the difference between EB7 and EB9?

  • EB7 is a slimmer design, made for the original class of lightweight E-motos such as the Surron Light Bee, Talaria MX3 and MX4 and the E-Ride Pro SS 2.0.
  • EB9 is the bigger brake designed to fit the higher-power, higher spec lightweight E-motos with larger brake mounts. It has a wider caliper and thicker pads.

Both brakes share the same master cylinder, piston size and pad surface area. Therefore the braking power provided by each brake is almost identical.

The EB9 is available in three different versions, depending on the post-mount size :

  • Arctic Leopard EX Pro S / Enduro – 90mm post mount – *in order to fit the dimensions of the bike, this version has a slimmer caliper than the other EB9 brakes *
  • Talaria MX5 & Altis Sigma – 95.5mm post mount
  • E-Ride Pro 3.0 & SR – 99.5mm post mount

Availability is being rolled out in phases, beginning with the EB7 and the EB9 version for E Ride Pro 3.0 and SR models (99.5 mm post mount). Additional EB9 mounting standards will follow as production expands.

How do I know which brake fits my bike?
You need to identify the post-mount spacing on your fork or brake adapter. You can measure this by using the following method:

  1. Remove your existing calipers, front and rear.
  2. Locate the two threaded holes on the fork leg and/or brake adapter where the caliper mounts.
  3. Measure the center-to-center distance between these two holes.

The measurement should match one of the following:

  • 74.2mm → EB7
  • 90mm → EB9 (Arctic Leopard version)
  • 95.5mm → EB9 (Talaria MX5 & Altis Sigma version)
  • 99.5mm → EB9 (E-Ride Pro 3.0 & SR version)

A digital caliper gives the most accurate result, but a ruler can work if you measure carefully. If your measurement is within ±0.5mm, it is likely correct.
If you are unsure, contact your Formula distributor or dealer before ordering — choosing the correct mount is essential for safe installation and performance.

Do I need an adapter to fit these brakes?
The brakes are designed as a direct replacement for OE systems on the listed models. If your E-Moto has not been modified, no additional parts are required.

If you have changed wheels, forks, or discs, always measure carefully and confirm compatibility before installation.

If you have upgraded to the TECH Suspension E39 Fork:

  • EB7 – requires a 203mm adapter. (Formula part no. F260169)
  • EB9 – requires the relevant TECH Suspension adapter for your moto (Talaria MX5, Altis Sigma, Arctic Leopard or E Ride Pro)

What rotor sizes can I use?

  • EB7: 220mm rotors (without adapters), up to 260mm with adapters (*see NOTE below)
  • EB9: 220mm rotors (without adapters), up to 260mm with adapters.

Disc sizes above 220mm require an adapter. EB7 and EB9 are compatible with discs up to 260mm.

Both systems support a maximum rotor thickness of 3mm.

If you have changed wheels, forks, or discs, always measure carefully and confirm compatibility before installation.

*NOTE: The EB7 design includes a ‘step up’ in rotor size. This means when fitting the EB7 brake:

  • 220mm disc requires a 203mm adapter (Formula part no. F260169)
  • 240mm disc requires a 220mm adapter (Formula part no. F260161)

Alternatively you can change the size of your disc instead of the adapter.

Are the brakes pre-bled and ready to install?
Formula brakes come assembled and pre-bled from the factory, but if you cut hoses to adjust length, a bleed is required to remove air and ensure consistent brake feel. For safety and best performance, Formula recommends hose shortening is carried out by an authorised dealer or experience mechanic.

Are these brakes suitable for off-road riding?
Yes. Both systems are built for demanding off-road use, featuring CNC-machined aluminum calipers, braided steel hoses, and sintered pads for consistent performance in dirt, mud, and high-heat conditions.

Still unsure which brake to choose?
If you’re unsure after measuring:

      • Take a clear photo of your fork mount and/or brake adapter
      • Note your current rotor size
      • Contact your Formula dealer or distributor for guidance

Choosing the correct mount size ensures proper fit, performance, and safety.
