Fastace AHX12RV Fork for Surron, Talaria & E-Ride Pro
Take your electric dirt bike to the next level with the Fastace AHX12RV — one of the most durable and race-proven fork upgrades available for Surron, Talaria, and E-Ride Pro platforms. Designed to outperform standard MTB-style forks, this fork brings true moto suspension engineering to your eMoto.
The AHX12RV fork features a heavy-duty open-bath damper in one leg with a motorcycle-style shim stack and coil spring in the other, delivering consistent, plush travel that soaks up everything from hard enduro rock gardens to high-speed jump landings. With tool-free rebound and compression adjustability, you can dial in your ride exactly the way you like it.
If you're still running the OEM RST Killah fork or similar, you're leaving performance on the table. The Fastace is a night-and-day upgrade built to handle real abuse.

🛠️ Install Notes:
We recommend professional installation unless you have experience with MTB or moto fork setup. The steering tube must be cut to your frame's specs, and a star nut needs to be properly seated. OEM Surron and Talaria headsets are fully compatible — no headset mods required.
Pro Tip: Pair this fork with a Fastace Drop Crown Triple Clamp if you’re running a 21" front wheel or want extra rake adjustability.

⚡ Real Rider Feedback:
“The Fastace is the first fork I’ve ridden that actually makes my Surron feel like a real dirt bike. The stiffness and confidence when charging through rock sections is insane. After a full weekend of hard trail riding and jumps, no leaks, no flex, and it just feels planted.”
— Jared W. (Hard Enduro Rider, Ohio)
🧠 Why Choose Fastace 3.0 Over Fox40, RST, or DVO?
While forks like the Fox40 are legendary in the downhill MTB scene, they weren’t built for the heavier, high-torque abuse of electric dirt bikes. The Fastace fork is heavier by design — prioritizing strength and stiffness over weight savings.
Most MTB forks flex or blow seals under real moto loads — and some brands (including Fox) even void warranties when used on eMotos. Fastace doesn’t just survive — it thrives under pressure.
🔥 FAQ
Q: Is this fork better than the stock RST on my Surron or Talaria?
A: Absolutely. The RST is known for flex and durability issues. The Fastace fork offers better damping, strength, and ride feel right out of the box. It’s one of the best upgrades for your ride.
Q: Can I run this with a 21" front wheel?
A: Yes, but you’ll need the Fastace Drop Crown to maintain proper clearance and steering geometry.
Q: Do I need a new headset or stem?
A: No. The Fastace fork is compatible with your OEM Surron or Talaria headset and stem. Just make sure your steerer tube is cut properly and spaced correctly.
