Top 5 Surron Light Bee X Upgrades: Best Aftermarket Brands to Know
The Surron Light Bee X is one of the most exciting electric dirt bikes ever built. It's lightweight, torquey, and incredibly versatile — whether you're shredding singletrack, hitting a motocross track, or carving through open desert. But if you've spent any real time on a Light Bee X, you already know it has a ceiling. The stock components, while functional, leave serious performance on the table.
The good news? The Surron aftermarket is absolutely thriving. A dedicated community of riders and brands has built an entire ecosystem of performance parts specifically designed to transform the Light Bee X into something far more capable than what rolls off the factory floor. From massive power upgrades to suspension overhauls and full-size wheel kits, the options are better than ever in 2026.
Here are the top 5 Surron Light Bee X upgrades every serious rider should know — along with the specific aftermarket brands making the best products in each category.
1. Controller & Motor Upgrade — The Biggest Power Gains Start Here
If there's one upgrade that fundamentally changes what your Light Bee X is capable of, it's the controller and motor combo. The stock setup caps you at a modest power output that feels fun at first but becomes limiting fast. Swapping to a high-performance aftermarket controller unlocks dramatically higher phase current, advanced throttle mapping, regenerative braking control, and the ability to run higher-voltage batteries.
EBMX — The Gold Standard for Light Bee Power Upgrades
When riders talk about controller upgrades, EBMX comes up first, and for good reason. Their X-9000 V3 Controller Kit is widely regarded as the top plug-and-play performance controller for the Surron Light Bee X. It's robust, feature-packed, and built with future upgrades in mind — meaning if you plan to eventually go to a higher-voltage battery or a race motor, the X-9000 V3 will grow with your build.
EBMX also produces two versions of their highly regarded XLB-60 Motor: the Core and the Race. The XLB-60 Race Motor is engineered for maximum RPM and top speed, pushing the torque band all the way to 13,000 RPM and delivering 42kW of peak power. The stator size has been increased from 60mm to 65mm compared to stock, and a 1mm air gap improves heat dissipation — critical for aggressive riding. Riders pairing the XLB-60 Race Motor with a 72V battery and the X-9000 V3 controller regularly report reaching 65 mph with the right sprocket setup.
The TORP TC1000 Controller, also available through DarwinEV, is another elite option. It offers smooth, precise control and pairs with an advanced smartphone app for real-time tuning. For riders who want deep tunability without going all-in on the EBMX ecosystem, the TORP is an excellent alternative.

2. Battery Upgrade — Unlock True Performance and Range
The factory 60V battery on the Light Bee X is the second biggest bottleneck in your stock drivetrain. Upgrading to a 72V or even an 81V pack doesn't just extend your range — it raises the ceiling on everything else. More voltage means more speed, more torque, and the ability to feed a high-performance controller the power it needs to really shine.
Nexbat — High-Quality Cells at the Right Price
Nexbat (distributed prominently through DarwinEV) has become one of the most respected battery brands in the Sur Ron community. Their lineup includes the 72V 50Ah Standard Battery loaded with Samsung 50S cells for balanced range and reliability, and the 72V 50Ah Pro Battery using Molicel P50B cells for higher output during aggressive riding. For riders chasing top-end speed, Nexbat's 81V 45Ah Standard and Pro packs add headroom that the 72V setup simply can't match.
NAB — Purpose-Built for Performance
NAB (North American Batteries) takes things further with race-oriented packs like the 72V 45Ah Quantum, rated at 70kW+ peak output, and the 72V MX Race Battery delivering 29kW continuous. For long-distance trail riding, the 72V 57Ah Expedition Battery is a standout option. These packs are available through Charged Cycle Works and represent some of the most powerful drop-in solutions for the Light Bee X platform.
DHS also deserves a mention here — their 80V 45Ah Race Battery uses RS50 cells and peaks at 44kW, making it one of the most aggressive stock-replacement packs on the market.

3. Suspension Upgrade — Handle the Power You Just Added
More power without better suspension is just a recipe for a sketchy ride. The stock KKE forks on the Light Bee X are functional for casual trail riding, but they weren't designed for the demands of aggressive off-road use — especially once you start pushing 50+ mph with a full power build. Upgrading your suspension transforms the way the bike feels beneath you: more planted, more precise, and dramatically more confidence-inspiring.
KKE — Affordable, Purpose-Built, and Proven
KKE Racing is actually the OEM suspension and wheels supplier for Sur Ron, which gives them a unique advantage — they know this platform better than almost anyone. Their Gold Series Front Suspension Fork for the Light Bee X is a major step up from the stock setup. Revised extensively for 2024, it features stronger construction, superior rigidity with less flex, 210mm of travel, an inverted design for stiffness and precision, 7050 aluminum outer tubes, NOK oil seals from Japan, and a stiffer 50lb spring (compared to the stock 40lb). Compression adjustment is built in, and the fitment is direct — no modifications needed.
For riders who want to maximize value and get a genuine improvement without a huge investment, KKE's upgraded forks are the go-to recommendation.
EXT Racing Shox — Premium Suspension for Serious Riders
For riders ready to invest in true performance suspension, EXT Racing Shox is the brand the serious e-moto community points to. Their Ferro Fork, available through DarwinEV and Electric Cycle Rider, is a purpose-built unit designed for the demands of electric dirt bike riding. It delivers exceptional damping, full adjustability, and the kind of feedback-rich performance you'd expect from a high-end motocross fork. If you've upgraded your power system and you're now riding faster and harder, the EXT Ferro is where your suspension budget should go.
FastAce forks — including the ECR Factory Tuned FastAce 2.0, custom-valved specifically for the Light Bee X — round out the suspension options for riders seeking a middle ground between KKE's value and EXT's premium performance.

4. Wheels & Tires — Go Full-Size and Never Look Back
The stock 19"/16" wheel setup on the Light Bee X is one of its most noticeable limitations for riders coming from traditional dirt bikes. The smaller wheels restrict your tire options, reduce stability at speed, and limit clearance on technical terrain. Upgrading to full-size 21"/18" wheels is one of the most transformative changes you can make to the bike's character — it immediately feels more like a real dirt bike.
Warp9 — The Benchmark for Sur Ron Wheel Kits
Warp9 Racing is the undisputed leader in Sur Ron wheel upgrades. Their Pre-Built 21"/18" Wheelset is a ready-to-ride solution for riders who want full motocross-sized wheels and access to a much wider range of tire choices. Available in multiple hub color options (black, blue, red) and rotor size configurations, the Warp9 wheels are precision-built to fit the Light Bee X with no modifications. For riders who want something truly custom, Warp9 also offers a Custom Wheel program where you can spec out your exact build.
The benefits go beyond tire selection. The larger wheel diameter smooths out trail chop, improves high-speed stability, and gives the bike a more planted feel in corners. Most serious Light Bee X builds eventually include Warp9 wheels as a cornerstone component.
KKE — Best Budget Option for Full-Size Wheels
KKE also produces a well-regarded 21"/18" wheel kit for the Light Bee X at a significantly lower price point than Warp9. For riders building their first Light Bee X upgrade or working with a tighter budget, the KKE wheels represent outstanding value — the same brand that supplies Sur Ron's factory, now offering full-size fitment.

5. Ergonomics & Controls — Warp9's Handlebars and Stem System
Once the major performance upgrades are in, your riding position becomes the final piece of the puzzle. The stock Light Bee X handlebars are narrow, low, and designed for a small, compact riding posture that doesn't suit every rider — especially adults standing 5'10" or taller. Upgrading to proper ergonomics reduces fatigue, improves control, and makes longer rides genuinely enjoyable.
Warp9 — The Definitive Ergonomics Brand for Sur Ron
Warp9 Racing dominates this category the same way they dominate wheels. Their flagship handlebar upgrade, the 3" Rise Handlebar, is made from 7075-T7 aluminum — one of the strongest aluminum alloys available — with a full anodized finish, a tapered tube design for the ideal balance of strength and flex, and a 31.8mm center clamp that fits the Light Bee X's OEM stem directly. At 770mm wide with a 9-degree backsweep and 5-degree upsweep, the geometry promotes a natural, relaxed hand position that dramatically reduces wrist fatigue on long rides.
Pair these bars with the Warp9 Direct Bar Mount Stem, which moves the bars 10mm forward and offers adjustable height (OEM low position or an additional 20mm rise with the included spacer). The stem is compatible with virtually every performance fork on the market — EXT Ferro, Fox 40, Manitou Dorado, DNM, DVO, and KKE — making it the connective tissue of a well-built Light Bee X ergonomic package.
Warp9 also produces a Stemlock to prevent handlebar slippage at high speeds, a common issue on the stock setup. It's an inexpensive add-on that every upgraded Light Bee X should have.
