RacingBros SCOUT43 Adjustable Front Fork – Surron Ultra Bee

The stock Ultra Bee fork gets overwhelmed quickly. It wasn’t made for the hits that the bike’s torque lets you go after. The RacingBros SCOUT43 is a bolt-in, fully adjustable 43mm fork made for e-moto riders who need real MX-level damping without a custom build.

It uses RacingBros’ race-proven Scepter 25 sealed cartridge: a 25mm piston, independent high- and low-speed compression, 21-click rebound, and 12-click hydraulic bottom-out control. The cartridge is sealed against contamination, so damping stays consistent when the trail gets ugly.

The chassis is built for braking loads. It has 43mm high-tensile alloy steel stanchions (>1200 MPa), 7050-T651 aerospace-grade upper tubes, and precision-forged 6061-T6 triple clamps and fork bottoms. The result is a stiff front end with sharp steering feedback.

It’s plug-and-play. It swaps directly for the OEM fork and works with your stock brakes and fender. The stock caliper adaptor is included.
