The Surron LBX is one of the most modified electric dirt bikes in the world, and for good reason. The stock bike is light and fun, but a few well-chosen upgrades turn it into something that climbs harder, stops faster, handles bigger jumps and suits your height and weight properly. This guide covers the 12 Surron LBX upgrades we recommend most, in the order we’d fit them.
Whether you own a 2024, 2025 or 2026 model, the same principles apply: fix the contact points first, then protection and brakes, then suspension, and only then add power. Power without brakes and suspension to match is how bikes and riders get broken.
What does Surron LBX mean?
LBX is short for Light Bee X (see the official specs), Surron’s lightweight off-road electric motorbike. You’ll see it written as Surron LBX, Sur-Ron LBX, SurRon Light Bee or just “the Bee”. It’s the same bike. If you want the full specs and a review of the latest model, read our 2026 Surron Light Bee X review. This article is all about making the bike you already own better.
A quick model-year summary helps when choosing parts, because some upgrades are specific to the battery voltage and electronics:
| Model year | System | Stock peak power | Notes for upgrades |
|---|---|---|---|
| 2024 | 60V | 6 kW | Huge aftermarket, most parts fit |
| 2025 | 60V | 8 kW | Stronger stock controller |
| 2026 | 72V | 10 kW | New CAN Bus electronics, check compatibility |
Before you modify your Surron LBX
A few important points before you spend a cent:
- The Surron LBX is an off-road bike. It isn’t road registrable, and power upgrades don’t change that. More power just means more speed on private land and tracks. The official distributor explains why on its are Surron bikes street legal page.
- Warranty. Modifying the electrics or motor can affect the manufacturer’s warranty. Talk to us before you start if your bike is still covered.
- Safety first. Every power upgrade should be matched by better brakes, suitable tyres and suspension that suits your weight.
- Quality wiring matters. Poorly crimped connectors and under-rated cables cause most electrical problems on modified bikes.
1. Handlebars, stem and grips
The cheapest upgrade that makes the biggest difference is getting the cockpit right. The stock bars on a Surron LBX are narrow and low for most adults.
- MX bars – wider, stronger motocross-style bars give more leverage and control. Our 31.8 mm MX bars and 28.6 mm MX bars with mid rise are popular choices.
- Riser stems – raise and move the bars forward, which helps taller riders stand comfortably. See our direct mount riser stem.
- Grips – Pro Taper grips reduce arm pump and last longer than the stock grips.
Set the bars so they feel natural when you’re standing on the pegs, not sitting. That’s where you’ll spend most of your time on rough ground.
2. Foot pegs
The stock pegs are small and slippery when wet. Wider, sharper pegs give your boots far more grip and spread the load when you’re standing. Our premium foot pegs and brace bundle also strengthens the mounts, which is important if you jump the bike.
3. Seat height and comfort
Riders at both ends of the height range can change the seat. Taller riders like the RaceSpec Tall Boy MX seat or seat extenders, which add length so you can move around more. Shorter riders and teens can fit an LBX seat lowering kit to get their feet closer to the ground.
4. Protection: bash plate, guards and hand guards
The underside of a Surron LBX takes a beating on rocks and logs. Protection is cheap insurance.
- A bash plate protects the motor and frame.
- Hand guards protect your hands and the levers in a crash.
- A rear rotor guard stops the rear disc getting bent.
- A longer rear fender keeps mud off your back.
5. Brakes
Stock brakes are fine for stock power, but once you ride faster or heavier, they fade on long descents. Two upgrades make a big difference:
- Better pads – Shimano brake pads for the Surron LBX bite harder and last longer than many generic pads.
- Bigger rotors – our 250 mm front and rear rotor kit increases stopping power and heat capacity.
Bleed the brakes with fresh fluid when you fit new pads, and bed the pads in properly before riding hard.
6. Tyres
Tyres change how the bike behaves more than almost anything else. The stock tyres on a Surron LBX are a compromise. If you ride mostly dirt, a proper knobby like the Shinko 241 3.00-18 gives more grip in loose terrain. Heavy-duty tubes reduce pinch flats on rocky trails.
Many riders also fit a 21-inch front wheel, like our 21-inch LBX front wheel, which rolls over ruts and rocks more easily and opens up a much wider choice of motocross tyres.
7. Rear suspension
The stock rear shock is set up for lighter riders. If you’re over about 75 kg, or you jump the bike, rear suspension is where your money goes next.
- Stiffer springs – the cheapest fix if the bike sags too much.
- Upgraded linkage and triangle – changes the leverage ratio for better support and progression. See the EBMX upgraded race triangle and linkage.
- A new shock – such as the RFLOXA rear shock, for a big improvement in comfort and control.
8. Front forks
If you’ve upgraded the rear, the stock fork may feel soft or harsh by comparison. A fork upgrade like the RFLOXA Hawk31 with 203 mm travel balances the bike and handles bigger hits. Always set the fork and shock up together so the bike stays level.
9. Drivetrain: belt to chain conversion
The Surron LBX uses a belt for the primary drive. It’s quiet, but belts can stretch or snap under heavy use, especially after a power upgrade. A primary belt to 420 chain conversion kit is stronger and easier to maintain in the bush.
At the same time, look at sprocket sizing. A bigger rear sprocket gives stronger acceleration and a lower top speed, which suits tight trails. A smaller sprocket does the opposite. Our 58T steel sprocket is a common choice for trail riders.
10. Batteries for more range and power
The battery is the upgrade that most riders want, because it adds both range and power. A higher-voltage, higher-capacity battery lets the controller deliver more power without sagging.
- The Ride Longer 72V 63Ah LBX battery roughly doubles the energy of the stock 60V pack on older bikes.
- The MPE 60V 65Ah battery is a plug-in range upgrade for 60V bikes.
A 72V battery on a 60V bike usually needs a matching controller, and some batteries need a harness such as the QS8 harness upgrade. Always charge with the correct charger for your new battery.
11. Controller upgrades: the X-9000
The controller decides how much power reaches the motor. EBMX’s X-9000 is the best-known upgrade, and paired with the right battery it can turn a Surron LBX into a genuinely fast bike. Our custom build uses an X-9000 to make 13 kW.
You’ll need the controller, the correct harness for your bike and, usually, a display. Start with the X-9000 V3 Surron Light Bee harness and browse the full EBMX power upgrades range.
A controller upgrade is where good installation matters most. Poor connections can overheat, and incorrect settings can damage the motor. If you’re not confident with wiring, ask us about fitting.
12. Motor upgrades
For the ultimate Surron LBX, some riders replace the stock motor with a higher-output motor such as the EBMX XLB-60. This is a serious build, usually paired with an X-9000, a 72V battery, upgraded suspension and big brakes. It’s for experienced riders only.
Choosing upgrades for your riding style
The right parts depend on how and where you ride. Here’s how we’d prioritise for the most common types of Surron LBX owner.
Trail and bush riders
Trail riders spend long days on technical singletrack, so comfort, protection and range matter most. Prioritise bars and pegs, a bash plate and hand guards, a proper knobby rear tyre, and a rear spring or linkage that suits your weight. A larger battery is the next logical step, because running out of charge ten kilometres from the car is no fun.
Motocross and jump riders
If you ride a motocross track or build jumps on a property, suspension is everything. A stock rear shock bottoms out quickly on big landings. Budget for a stronger linkage, a quality shock and a fork upgrade, plus foot peg braces and a 21-inch front wheel. Only add power once the bike can handle the landings.
Taller and heavier riders
At over 180 cm or 85 kg, the stock Surron LBX feels small and soft. Fit higher bars and a riser stem, a taller or longer seat, stiffer suspension and bigger brakes. Many heavier riders eventually decide an Ultra Bee suits them better, and that’s worth considering before you spend thousands on upgrades.
Teens and smaller riders
For younger or smaller riders, focus on control rather than power. A seat lowering kit, smaller grips, softer suspension settings and the lowest power mode make the bike much less intimidating. Don’t add power until they’re confident, and make sure they wear full gear.
Setting up suspension after your upgrades
Fitting new suspension parts is only half the job. Setting them up for your weight is what makes them work.
1. Measure the rear wheel travel from the axle to a fixed point on the frame, with the bike on a stand.
2. Measure again with the bike on the ground and you sitting on it in your riding gear. The difference is rider sag.
3. Adjust spring preload until sag is roughly 25–30% of the total rear travel.
4. Set the fork sag and air pressure or preload so the bike sits level.
5. Adjust rebound so the bike doesn’t bounce after a bump, then fine-tune compression for the terrain.
Write your settings down. If the bike starts to feel wrong later, you’ll have a known baseline to go back to.
Upgrade mistakes to avoid
We see the same mistakes again and again:
- Adding power first. More power on stock brakes and suspension is a recipe for crashes.
- Cheap batteries with no track record. Poor-quality cells can fail early or, worse, become a fire risk. Buy from reputable brands with proper battery management systems.
- Mismatched parts. A 72V battery with a 60V controller, or a harness for the wrong model year, causes problems.
- Skipping the torque wrench. Over-tightened bolts strip threads and crack parts. Under-tightened ones fall out.
- Ignoring wiring quality. Loose or poorly crimped connectors create heat and intermittent faults.
Tools every Surron LBX owner should have
A small, good-quality tool kit covers most jobs:
- metric Allen keys and a set of Torx keys,
- a 3/8-inch socket set and a torque wrench,
- tyre levers, a pump and a pressure gauge,
- a chain breaker and spare master link if you’ve converted to chain,
- a brake bleed kit with the correct mineral oil or fluid,
- cable ties, electrical tape and a multimeter for basic electrical checks.
Keep a compact version of this kit in a backpack or bum bag when you ride, so a loose bolt or flat tyre doesn’t end the day.
Do upgrades add resale value?
Quality upgrades can help a bike sell faster, especially suspension, brakes and protection. Big power upgrades are more mixed. Some buyers pay a premium for a well-built X-9000 bike, while others prefer a standard bike with no questions about how it has been ridden. Keep receipts and a record of who fitted each part, as that reassures buyers.
If you plan to sell in the future, keep the original parts you’ve removed. Being able to return the bike to standard broadens the pool of buyers.
Recommended upgrade paths by budget
Not sure where to start? Here are three paths we recommend.
| Budget | What to fit | Result |
|---|---|---|
| Under $500 | Bars, grips, pegs, brake pads | Better control and comfort |
| $500–$2,000 | Add protection, tyres, rear spring or linkage, rotors | Safer, more capable trail bike |
| $2,000+ | Add battery, X-9000 controller, fork or shock | Big gains in power and range |
Which upgrades change how the bike behaves the most?
If you only do three things, do these:
1. Fit bars and a stem that suit your height.
2. Set the suspension up for your weight.
3. Upgrade the brakes before adding power.
Those three changes transform how a Surron LBX feels, and they make it safer too.
Fitting upgrades yourself vs using a workshop
Most of the bolt-on upgrades, such as bars, grips, pegs, guards and brake pads, are well within reach of a confident home mechanic with basic tools. Suspension, battery and controller upgrades are more involved. Wiring mistakes can damage expensive parts, and incorrect suspension setup can make the bike unpredictable.
If you’re not sure, contact us and we’ll recommend parts that suit your riding and point you in the right direction for fitting.
Keeping a modified bike reliable
Modified bikes need a bit more attention:
- Check electrical connectors and cable routing after the first few rides.
- Re-torque bolts on new parts after the first ride.
- Check chain tension and wear more often if you’ve added power.
- Monitor battery and controller temperatures in hot weather.
- Keep a record of every part you’ve fitted, which helps with future servicing and resale.
Riding a modified bike safely and responsibly
A modified Surron LBX can be much faster than the stock bike, so ride within your limits and be a good ambassador for electric dirt bikes.
- Always ride on private property with the owner’s permission, or at approved off-road parks and tracks.
- Wear a certified helmet, goggles, gloves, boots and body protection. Our dirt bike gear guide explains the essentials.
- Remember that other trail users can’t hear you coming. Slow down around walkers, horses and cyclists.
- Keep noise and dust away from neighbours, and respect property boundaries.
- Don’t lend a heavily modified bike to an inexperienced rider.
Riding responsibly helps keep private land and off-road parks open to everyone. The more riders behave well, the easier it is for landowners and councils to say yes to electric dirt bikes.
