RFLOXA Hawk31 Max Black USD front fork (inverted front fork) is built to fit Talaria MX3 / MX4 / XXX / XXX Pro, SurRon LBX / LBS / L1E, and E-Ride Pro S / SS 1.0 / SS 2.0 electric enduro and dirt bikes (e‑moto). It is an oil–spring fork (oil-spring fork) designed around the geometry of Talaria Sting MX3/MX4, Sur-Ron Light Bee, and Eride Pro platforms.
This Hawk31 Max comes as a complete kit with a wider drop crown triple clamp set (triple clamp kit). The clamp geometry follows the listed bikes, so non-standard front hubs (wheel core) or modified wheels that do not match factory dimensions may not align correctly.
The fork uses multi-way damping (multi-way damping) with adjustment for high-speed compression (HSC), low-speed compression (LSC), rebound (rebound damping), and spring preload (spring preload). Travel is configurable as 203 mm or 228 mm main piston travel.
Benefits of the RFLOXA Hawk31 Max USD Fork
- Inverted USD oil–spring design – uses an inverted (USD) oil–spring architecture intended for e‑moto load cases.
- HSC and LSC compression adjustment – provides high-speed compression (HSC) and low-speed compression (LSC) tuning on one fork.
- Rebound damping adjustment – lets you set fork return speed to match your riding pace on enduro or track use.
- Spring preload adjustment – changes initial spring tension to suit rider weight and setup preference.
- 203 mm or 228 mm travel options – main piston travel supports two configurations: 203 mm or 228 mm.
- AL6061-T6 forged bottom brackets – lower mounts (bottom brackets) use AL6061-T6 forged aluminum alloy.
- AL7075-T6 internal tubes – inner fork tubes are AL7075-T6 aluminum, selected to increase stiffness.
- 74 mm brake mount for 203 mm rotor – caliper mount spacing is 74 mm and targets a Ø203 mm brake disc with upgrade potential.
Who is this for?
This RFLOXA Hawk31 Max USD fork is for riders building or upgrading a SurRon, Talaria, or E‑Ride Pro platform with a moto-style inverted fork (USD fork). The manufacturer lists it for electric dirt bikes (electric dirt bikes) and downhill bikes (downhill bikes), which makes it relevant for e‑moto builds and DH conversions that use these fitments.
Compatible models (fitment bike list): Talaria MX3, Talaria MX4, Talaria XXX, Talaria XXX Pro, SurRon LBX, SurRon LBS, SurRon L1E, E-Ride Pro S, E-Ride Pro SS 1.0, E-Ride Pro SS 2.0, Rawrr Mantis, Rawrr Mantis X, 79 Bike Falcon M, 79 Bike Falcon PRO, 79 Bike Falcon GT, Ventus One, Ventus One Plus, RFN Apollo, Rerode R1, and SRPNTMOTO.
Ventus One Plus installation requires an 8 mm spacer, as specified by the manufacturer. The included wider drop crown triple clamps are based on Talaria Sting MX3/MX4, Sur-Ron Light Bee, and Eride Pro geometry, so wheel and hub changes outside factory dimensions can affect fit.

Why choose the Hawk31 Max kit?
The Hawk31 Max combines a USD inverted chassis with an oil–spring layout and multi-way damping controls in one package. The adjusters cover HSC, LSC, rebound, and spring preload, which are the exact tuning points riders use when adapting a fork to e‑moto weight and speed.
This kit also includes the wider drop crown triple clamps that follow Talaria Sting MX3/MX4, Sur-Ron Light Bee, and Eride Pro geometry. That clamp choice is intended to keep the front end layout consistent with those platforms, while still supporting a 74 mm caliper mount with a Ø203 mm rotor interface that can be upgraded.
The manufacturer notes a real-world comparison from zeekster’s track test of the Hawk31 Max against higher-priced suspension. The quote provided is: “This is the next best thing to EXT and for the price, it is so much better!” – zeekster.
