RFloXa Ultra43

RFloXa Ultra43 Fork for Surron Ultra Bee

The RFloXa Ultra43 is built for riders who want more control, more adjustability, and a stronger front-end setup on their Surron Ultra Bee. With reinforced 43mm fork tubes, 251mm of travel, premium seals, CNC-machined components, and multiple damping adjustments, this fork is designed for serious off-road riding, jumping, enduro use, and riders who are ready to push their Ultra Bee harder.

If your stock front suspension is feeling soft, vague, or just not keeping up with how you ride, the Ultra43 brings a much more tunable and planted feel to the bike.

Important Installation Note

When installing the RFloXa Ultra43 Fork on a Surron Ultra Bee, the Surron Ultra Bee OEM Headset Assembly is needed for proper installation.

We recommend adding the headset assembly to your order so you have the correct seals, races, bearings, spacer, and steering stem hardware ready for the fork swap.
