Formula EB7 E-Moto Brake System | Surron, Talaria, E Ride Pro, Ventus & Rerode

The Formula EB7 E-Moto Brake System was developed specifically for the original class of lightweight electric motorcycles. Formula engineered the EB7 around the common 74.2 mm post mount used by bikes such as the Surron Light Bee, Talaria Sting MX3 and MX4, and E Ride Pro SS 2.0.

Designed and manufactured in Italy, the EB7 combines a slim profile with the stiffness and hydraulic consistency needed for demanding off-road riding. Its caliper body is CNC-machined from aeronautic-grade Ergal 7075 aluminum, then finished with black anodizing for additional surface protection. This construction helps maintain a solid, predictable brake feel when the trail gets rough or temperatures begin to climb.

Controlled Power for Lightweight E-Motos

The EB7 uses four 22 mm pistons in the front caliper and two 22 mm pistons in the rear. This configuration provides strong braking force while keeping modulation smooth and manageable. Modulation lets you adjust braking pressure progressively, which helps when traction changes through loose corners or steep descents. Phenolic pistons help control heat transfer through the caliper, while sintered brake pads provide dependable wear life and braking performance in dirt, mud, and high-temperature conditions.

Forged aluminum master cylinders and adjustable ball-end levers give the system a refined lever feel without unnecessary bulk. Steel-braided brake hoses with PTFE inner liners resist expansion under pressure, helping the brakes deliver consistent engagement during repeated hard stops and aggressive trail riding.

The result is a compact e-moto brake system built for precise lever control and consistent performance under heat, with a caliper sized for supported 74.2 mm platforms.

Bike Fitment

• Surron Light Bee.
• Talaria Sting MX3.
• Talaria Sting MX4.
• E Ride Pro SS 2.0.
• Ventus V1.
• Ventus V1+.
• Rerode R1.
• Rerode R1+.
• Original Rawrr Mantis with 74 mm brake mounts: Front fitment only. The rear brake mounts on the opposite side of the bike, so the Formula EB7 rear brake assembly will not fit. Verify the front mounting-hole spacing, required rotor and adapter combination, and caliper clearance before ordering.
• Other compatible lightweight e-motos using a 74.2 mm brake post mount, with the correct rotor, adapter, caliper clearance, and hose routing.

Matching bolt spacing is only part of confirming fitment. Check the complete mounting arrangement before ordering, including which side of the bike the caliper mounts on. Spacers alone do not guarantee compatibility.

Fitment Exclusions

• Original Rawrr Mantis rear brake mount, including models with 74 mm mounts, because the rear brake is positioned on the opposite side.
• Arctic Leopard EX Pro S and Enduro models using 90 mm post mounts, which require the appropriate Formula EB9 version.
• Talaria MX5 and Altis Sigma models using 95.5 mm post mounts, which require the appropriate Formula EB9 version.
• E Ride Pro SS 3.0 and SR models using 99.5 mm post mounts, which require the appropriate Formula EB9 version.

Important Rotor and Adapter Requirements

The specified setup for supported lightweight e-motos is a 220 mm rotor at the front and rear. Although the EB7 caliper accommodates several rotor diameters with the correct mounting configuration, these applications require the specified 220 mm setup for proper braking performance. The original Rawrr Mantis remains a front-only application for this brake system.

If you are installing a 220 mm front rotor with the Tech E39 fork, you must use Tech’s 203 mm brake mount adapter for proper caliper alignment and fitment. Using the wrong adapter may cause mounting problems, incorrect pad contact, or improper brake operation.

The EB7 mount design includes a step up in rotor size. A 220 mm rotor requires a 203 mm adapter, while a 240 mm rotor requires a 220 mm adapter. Depending on the bike and mounting arrangement, changing the rotor size may be an alternative to changing the adapter. Always verify the complete fork, adapter, rotor, and caliper combination before riding, while following the specified rotor requirements for your application.

Formula EB7 vs. Formula EB9

The EB7 is the compact option for lightweight e-motos using a 74.2 mm post mount. The EB9 is designed for newer, higher-power platforms with larger brake mounts. It uses a wider caliper body and thicker pads to suit those applications.

Both systems use the same master cylinder, piston size, and brake pad surface area, providing nearly identical braking power. The main differences are physical fitment, caliper width, pad thickness, and the post-mount size required by the bike.

• 74.2 mm post mount: Formula EB7.
• 90 mm post mount: Formula EB9 for Arctic Leopard EX Pro S and Enduro models, using a slimmer version of the EB9 caliper for clearance.
• 95.5 mm post mount: Formula EB9 for Talaria MX5 and Altis Sigma.
• 99.5 mm post mount: Formula EB9 for E Ride Pro SS 3.0 and SR.

Formula EB7 and EB9 availability is being introduced in phases, beginning with the EB7 and the EB9 version for E Ride Pro SS 3.0 and SR models.

How to Identify the Correct Brake

1. Remove the existing brake caliper.
2. Locate the two threaded mounting holes on the fork or brake adapter.
3. Measure the distance from the center of one hole to the center of the other.
4. Match that measurement to the appropriate EB7 or EB9 version listed above.
5. Confirm your current rotor diameter and the adapter required for that rotor.
6. Check the caliper mounting side, especially on an original Rawrr Mantis, where compatibility is limited to the front.

If you are still unsure, take a clear photo of the fork mount, record the current rotor size, and contact your dealer or distributor before installation. Correct mount spacing, rotor diameter, and adapter selection are all necessary for safe alignment and dependable braking.

Installation and Service Notes

Formula EB7 brakes arrive pre-assembled and pre-bled. If either hose must be shortened during installation, the brake will need to be bled afterward to remove air and restore a firm, consistent lever feel. Brake installation is a safety-critical job, so all mounting hardware, hose routing, rotor alignment, and lever operation should be inspected before riding.

The EB7 stands out through its combination of rigid 7075 aluminum calipers, heat-managing phenolic pistons, forged controls, and steel-braided hoses. Those components support controlled braking and consistent feedback without unnecessary size or weight on a lightweight electric motorcycle.

Who Is the Formula EB7 Best For?

• Aggressive trail riders: Riders who need predictable modulation, heat control, and durable sintered pads in dirt and mud.
• Lightweight e-moto owners upgrading stock brakes: Riders looking for a purpose-built 74.2 mm system with precise fitment, subject to the front-only Rawrr Mantis limitation above.
• Riders who value consistent lever feel: Owners who want forged controls, braided hoses, and CNC-machined Italian calipers in a compact package.
