RFlo-Xa Hawk31 Max 203mm Travel Fork (45–60lb Progressive Spring)
The RFlo-Xa Hawk31 Max is one of the most impressive long-travel fork upgrades hitting the Surron/ebike scene right now. With a massive 203mm of plush, controlled travel and a 45–60lb progressive coil spring, this fork is built for aggressive riders who want better stability, smoother landings, and more confidence at speed. Here’s my full breakdown after real-world testing.
⚡ Why Upgrade
If you're still running a stock fork, you already know the limitations—harsh bottom-outs, flex under heavy braking, and sketchy high-speed chop. The Hawk31 Max addresses all of that with:
- Huge 203mm travel for soaking up jumps, drops, and rough terrain.
- Progressive 45–60lb coil that stays supple off the top but ramps up for big hits.
- Stiffer chassis for more control during aggressive riding.
- More predictable rebound and compression compared to stock options.
If you're pushing your bike harder or riding trails that punish your front end, this upgrade is a game changer.
🛠️ What’s Included / Installation
The kit includes everything you need to get rolling:
- Hawk31 Max fork assembly
- 45–60lb progressive spring (pre-installed)
- Thru-axle
- Basic mounting hardware
Installation is straightforward if you're familiar with fork swaps. The steerer comes long enough for most setups, and the crown race fit is standard. Budget around 30–45 minutes with basic tools. I recommend torqueing everything properly and checking sag after your first ride.
🚀 Performance
This is where the Hawk31 Max really shines. On the trail, the fork feels buttery smooth with excellent small-bump sensitivity. The progressive spring gives you:
- Soft initial travel for chatter and roots
- Controlled mid-stroke support
- Hard-charging bottom-out resistance for jumps and drops
High-speed stability is noticeably better than stock, and the fork tracks straight through rough terrain. Landings are smoother, braking feels more consistent, and the overall ride inspires more confidence.
💎 Build Quality
The machining, anodizing, and overall finish look clean and premium. The fork feels solid with no unwanted flex, even for heavier riders. The seals and bushings feel tight, and the damping cartridge performs surprisingly well for this price range. It’s a durable setup that should hold up to aggressive riding.
✅ Who It’s For
- Riders jumping, hitting drops, or pushing their Surron/ebike hard.
- Heavier riders who need more support than stock forks provide.
- Anyone wanting better control, comfort, and confidence off-road.
- Those tired of tuning headaches—coil spring simplicity just works.
🏁 Final Thoughts
The rfloxa Hawk31 Max is a serious upgrade that transforms the front end of your bike. The combination of 203mm of controlled travel, a progressive coil spring, and a solid chassis makes it a standout option for riders who want reliability and performance without overspending.
I personally use this product and recommend it. If you want a fork that delivers smooth travel, great support, and a confidence boost on every ride, the Hawk31 Max is absolutely worth it.
