EXT Ferro EMX Fork

The EXT Ferro EMX is a premium inverted dual-crown fork engineered for maximum stiffness, precision, and control on modern lightweight e-moto platforms. Built with race-level suspension architecture, it delivers exceptional damping control, reduced flex, and consistent performance under aggressive riding conditions.

Designed for riders pushing performance limits, the Ferro EMX combines advanced air-spring technology with a high-flow 3-way cartridge damper system for refined handling across technical terrain and high-speed use.

Key Features

Dual Crown Inverted MX Architecture

Robust USD dual-crown design built for maximum torsional rigidity, stability, and front-end precision under heavy loads.

36mm Heat-Treated Chromed Stanchions

Constructed from heat-treated 42CrMo4 steel with Superfinish coating for reduced friction and long-term durability.

HS3 Twin Air Spring System

• Dual positive air chambers + large self-balancing negative chamber
• Optimized support across full travel range
• Improved sensitivity and mid-stroke control

High-Flow 3-Way Cartridge Damper

Independent high-speed compression, low-speed compression, and rebound adjustment for full suspension tuning control.

External Air Pressure Release System

Pressure release valves on both legs for consistent performance and reduced internal pressure buildup.

Boost-Compatible Axle System

Twin hexagonal floating axle with Ø20mm Boost spacing for increased wheel compatibility and stiffness.

Advanced Bushing Guidance System

CGB continuously guided DU bushing system with extended overlap for maximum chassis stiffness and steering precision.

Premium Sealing & Flow Design

Aviation-grade sealing system with self-hydraulic cartridge bleeding to reduce cavitation and hysteresis.
