EXT Ferro E-MX Fork

for Sur-Ron, Talaria, E Ride Pro, Etc

Developed by the team at EXT Racing Shox, the FERRO USD 36 is a premium 205mm travel upside-down fork designed to push the limits of e-moto performance. Built with cutting-edge suspension technology, this fork is a direct result of decades of motorsport innovation—now purpose-built for electric dirt bikes like the Sur-Ron Light Bee, Talaria MX3 / MX4, E-Ride Pro series, and more.

Whether you're racing, freeriding, or bombing rugged backcountry terrain, the FERRO delivers unmatched stiffness, bottom-out control, and tuning flexibility. It’s built to elevate every part of your ride—from control under braking to support during jumps and landings.

NOTICE: If you are running a stock wheel or a wheel that is not specifically designed for use with BOOST hubs you will need to install a rotor adaptor that is available HERE

Dont Forget to get your headset bearings Here.
These do not come with Bearings.

The Ultimate Inverted Fork Upgrade for High-Performance Electric Dirt Bikes

Some bikes such as the Altis Sigma, SRPNT Moto, E-Ride Pro SS 3.0, and E-Ride Pro SR require a brake adapter that is in development. Contact us for support or pre-order solutions.

Why Choose the FERRO?

When EXT Racing Shox saw the rise of high-torque electric motos, they answered with a fork designed from the ground up to handle the demands of today's fastest, heaviest e-motos. The FERRO uses race-proven tech from World Rally Championship suspension and adapts it into a fork that doesn’t compromise.

The HS3 hybrid spring system gives you unreal support near sag and full control at bottom-out. The high-flow damper cartridge brings razor-sharp response and tuning capabilities typically reserved for top-level motorsports.

  ⚠️ Fitment Notes & Required Adapters

  • If using non-Boost 110mm wheels (like stock Sur-Ron, Talaria, or ERP wheels), you'll need a Warp 9 Rotor Adapter – available here

  • Headset bearings are not included – Add them here
