What bikes does the RFloXa Ultra43 fork fit?
- Sur Ron Ultra Bee
Why choose the Ultra43 for an Ultra Bee?
RFloXa built the Ultra43 specifically for the Sur Ron Ultra Bee as a premium inverted fork with a reinforced 43 mm chassis engineered for aggressive trail riding, enduro and off-road use. It gives 251 mm of travel, and the reinforced triple clamp adds stability under hard braking and rough landings. RFloXa describes it as a direct upgrade path for Ultra Bee riders who want to improve front-end feel and confidence.
How does the Ultra43 adjust to rider weight and terrain?
Four adjusters are independent: preload, rebound, high-speed compression and low-speed compression, which gives precise control across a wide range of terrain and conditions. Before any of those are touched, the fork is ordered in a 24 lb, 27 lb or 30 lb spring rate so the base setup matches rider weight and terrain preference.
What makes the Ultra43 last?
The fork tubes are DLC coated to reduce friction and extend service life, and SKF oil seals keep damping performance consistent over time. The lowers are CNC machined from AL6061-T6 aluminum to keep weight down without giving up rigidity, which is how a 43 mm inverted fork comes in at 20 lb.
Will my Ultra Bee brakes fit the Ultra43?
The Ultra43 is compatible with 240 mm brake rotors and uses 78.5 mm brake caliper spacing. Check the rotor size and caliper spacing on your bike against those two figures before ordering.
