For those electric dirt bike riders looking to upgrade their Surron Ultra Bee with a direct bolt-on, no-fuss fork, Sirris offers the solution with its F43 fork.
The Sirris F43 fork is purpose-tuned, pressure-balanced, and offers 9.7 inches of ultra-plush travel. This is the absolute best suspension for your Surron Ultra Bee and will completely transform your bike into a true proper dirt bike that can perform in any terrain.
The F43 is designed with aggressive riding in mind—and we will tune it to your exact specifications!
Here are some highlights:
Plug & Play Installation: The F43 fork seamlessly integrates with the Surron Ultra Bee’s OEM front-end setup, factory compatibility with the OEM display, fender, and brake caliper. This is a direct swap for the stock Ultra Bee, with a pre-installed dust seal and headset bearing. Designed to fit directly with the Ultra Bee fairing and cable routing. No additional modifications are required.
Enhanced Front End: 43mm stanchions and robust upper fork tubes provide significant improvement in stability and strength while maintaining the bike’s turning radius.
Increased Travel: 9.67 inches of travel, 0.24 of an inch more than stock, offering extra cushioning, which is articularly beneficial for aggressive riding.
Hydraulic Bump Stop: Smoothly handles even the most forceful impacts at a maximum stroke, ensuring soft landings.
True Symmetrical Closed Cartridge: Ensures balanced load distribution and consistent performance, resistant to fade for predictable handling after extensive use. No matter how hard you ride or how many laps you take, closed cartridge will never fade and will always feel predictable.
Dual Oil Circuits: Separate lubrication and damping oils optimize damping performance without compromise.
High-Quality Materials: Made from 7000 series aluminum with Type 3 hard anodizing for strength and scratch resistance. Hard chrome stanchions and wrap-around guards extend performance lifespan.
Ultimate Suspension Tuning: Fully tunable valving for compression and rebound, with spring rates adjustable to your weight and riding style for a tailored suspension setup.
Lightweight: Each leg weighs only 8.8 lbs (4 kg), offering a powerful yet lightweight upgrade.
We highly recommend pairing your F43 Fork with the Sirris R46 Shock. Pressure balanced. Fully adjustable. Optimized for E-Moto. Revolutionize your bike's potential with harmonized suspension performance front and back. The ultimate suspension package is here.

"I got tracking for the warp9 rear wheel already. I’m so thankful! Can’t say thank you enough for all your help and for answering my questions so thoroughly.
The entire experience of doing business with you has been incredible. I honestly don’t remember the last time I received such great support from any company in any industry. I will most definitely be ordering from you in the future. Thank you so much!

"Your YouTube channel was essential for me learning about the Ultra Bee...The in-depth spec coverage, riding tests, range tests and upgrade reviews are great. Really good editing of the videos, too. Watching Tucker's riding, the footage is great and when you see a guy shred on these bikes, it gives you a really good feel for what these things are capable of... and makes me trust your guys' opinions. Keep up the good work!"
