RFLOXA Hawk31 Max Black is an inverted (USD) oil-spring front suspension fork built for Talaria MX3 / MX4 / XXX / XXX Pro, SurRon LBX / LBS / L1E, and E‑Ride Pro S / SS 1.0 / 2.0 electric enduro and electric dirt bike (e‑moto) platforms.
This Hawk31 Max uses an inverted oil-spring (oil-spring) damping layout that targets e‑moto loads. This kit includes the wider drop crown MAX triple clamp set with geometry based on Talaria Sting MX3 / MX4, Sur‑Ron Light Bee, and E‑Ride Pro frames.
The triple clamp and front-end geometry are platform-specific. A non-standard front hub or a wheel with modified, non-OE dimensions may not align correctly with this setup.
Benefits
- USD construction provides an inverted fork layout tuned for SurRon/Talaria/E‑Ride Pro style e‑moto chassis.
- High-speed compression (HSC) adjustment changes fork support under bigger hits and higher loads.
- Low-speed compression (LSC) adjustment tunes response during slow movements and weight transfers.
- Rebound damping adjustment lets you match return speed to riding pace and terrain.
- Spring preload adjustment helps set initial firmness for rider weight and setup.
- Adjustable travel supports 203 mm or 228 mm main piston travel configurations.
- Brake fitment support uses 74 mm caliper mount spacing for a ∅203 mm rotor, with upgrade potential.

Why choose
Hawk31 Max combines an e‑moto-focused oil-spring layout with a full adjustment range. HSC and LSC controls help set support and comfort separately for impacts and chassis movements.
The included wider drop crown MAX triple clamp set is CNC precision machined and matched to SurRon Light Bee, Talaria Sting, and E‑Ride Pro geometry. That pairing targets correct alignment on the listed platforms, while flagging fitment risk on custom hubs or non-standard wheels.
