This RFLOXA Hawk31 Max USD fork (inverted fork) + RAB53RV 265L rear shock (rear damper) kit fits SurRon LBX/LBS/L1E, Talaria MX3/MX4/XXX/XXX Pro, and E-Ride Pro S/SS electric dirt bikes (e-moto). It is a suspension upgrade set built around an upside-down front fork with a CNC triple clamp (triple clamp) and a matching RAB53RV shock.
The front fork provides 203–228 mm of main piston travel, and it includes damping adjustments for HSC, LSC, rebound, and spring preload. The RAB53RV rear shock uses an external nitrogen reservoir and an oil-gas separation damping structure.
This Hawk31 Max fork kit is supplied without the upper headset bearing. By default, the fork is also supplied without a pressed-in lower headset bearing to increase cross-model fitment, and a note can be added at checkout if you need the lower bearing pressed in.

Why Choose This RFLOXA Hawk31 Max Fork Kit
This RFLOXA Hawk31 Max USD fork and CNC triple clamp combination is specified with ∅37 mm inner tubes and 74 mm caliper mount spacing, which helps match the stated triple clamp geometry. The fork is also set up around a ∅203 mm front brake disc standard, while keeping the disc size upgradeable.
The RAB53RV 265L rear shock adds an external nitrogen reservoir and an oil-gas separation damping structure. Both ends specify 55CRSI spring wire, and the fork uses a split material approach with forged AL6061-T6 brackets and AL7075-T6 tubes.
Fitment flexibility is handled through the headset bearing approach. The fork does not include the upper headset bearing, and the lower bearing is not pressed in by default so it can be adapted to more models. If you need the lower bearing pressed in, you can leave an order note, but Talaria installations are advised to keep it unpressed due to the Talaria-specific lower bearing and spacer requirement.
