The Ultimate Torque Upgrade for Your Surron Light Bee
First, the 58 tooth sprocket and 112 link chain set is one of the most effective performance upgrades for your Surron Light Bee X, S, or L1E. The stock gearing is designed for balanced acceleration and top speed. However, installing a larger rear sprocket dramatically increases torque output at the expense of top speed. This trade-off is ideal for off-road riders, hill climbers, and anyone wanting explosive acceleration.
The complete set includes a 58-tooth rear sprocket and a 112-link 420 O-ring chain. The chain length is specifically matched to the larger sprocket for proper tension and fitment.
What’s Included in the Chain Set
A complete 58T sprocket chain set includes both components needed for installation :
| Component | Specification | Function |
|---|---|---|
| Rear Sprocket | 58 teeth, 7075-T6 aluminum | Increases torque and acceleration |
| Drive Chain | 420 size, 112 links, O-ring | Matches the 58T sprocket length |
The 58T sprocket is CNC-machined from billet aluminum for precision fitment . The 112-link chain is pre-sized for this specific sprocket configuration. No additional links are needed for installation.
58 Tooth Sprocket Specifications
Premium 58T sprockets are constructed from high-grade materials for durability :
| Feature | Specification |
|---|---|
| Material | 7075-T6 billet aluminum |
| Tensile Strength | 74,000 PSI |
| Yield Strength | 63,000 PSI |
| Manufacturing | CNC-machined |
| Finish | Anodized (black, blue, red, purple, pink) |
| Weight | 381g (0.84 lbs) |
| Position | Rear |
The 7075-T6 aluminum offers exceptional strength while keeping weight low . Unlike steel sprockets, aluminum won’t rust or corrode. The anodized finish provides a durable, scratch-resistant surface in multiple color options .
The precision engineering ensures excellent chain grip and reduced friction . Radial mud grooves etched inside the sprocket teeth shed dirt and grit, saving weight and increasing chain life .
112 Link 420 O-Ring Chain Specifications
The matching 112-link chain is designed specifically for the 58T sprocket setup :
| Feature | Specification |
|---|---|
| Chain Size | 420 |
| Link Count | 112 links |
| Type | O-ring sealed |
| Compatible Sprockets | 56T, 58T, 60T |
| Lubrication | Minimal required (O-ring sealed) |
The O-ring design seals lubricant inside the chain pins. This extends chain life significantly compared to non-sealed chains. Riders report 10x longer chain life in most conditions .
The 112-link length is the standard for 58T sprocket setups . If you’re switching from a smaller sprocket (like the stock 48T), you will need a longer chain. This set provides the correct length already.
Compatibility
This sprocket and chain set fits a wide range of electric dirt bikes :
| Model | Compatibility |
|---|---|
| Sur-Ron Light Bee X | 2019-2025 |
| Sur-Ron Light Bee S | Full compatibility |
| Sur-Ron Light Bee L1E | Full compatibility |
| Segway X160 / X260 | Same platform |
| Talaria Sting MX3 / MX4 | |
| E-Ride Pro S / Pro SS | |
| Rawrr Mantis X | 2024-2025 |
Some KKE sprockets also fit the Rawrr Mantis X (2024-2025) . Always verify your specific model year and chain size before purchasing.
Performance Benefits of 58 Tooth Sprocket
Installing a 58T rear sprocket provides several performance advantages over the stock 48T gearing :
Increased Acceleration:
- Significantly better off-the-line acceleration
- More responsive throttle feel
- Easier to pop the front wheel up
Better Hill Climbing:
- Improved torque for steep inclines
- Less strain on the motor when climbing
- Maintains speed better on long uphills
Enhanced Off-Road Capability:
- Excellent for technical trails where slow-speed control matters
- Reduces clutch slipping in tight sections
- More predictable power delivery
Lower Operating Temperatures:
- Motor works less to achieve same acceleration
- Controller runs cooler under load
- Extended component life from reduced strain
The 58T sprocket is considered ideal for off-road users over 113kg (250 lbs) and mixed-use riders between 95-108kg (210-240 lbs) . For extremely technical terrain, some riders even opt for 60T or 64T sprockets.
Performance Trade-Offs
Every performance modification comes with trade-offs :
| Trade-Off | Impact |
|---|---|
| Reduced Top Speed | Lower maximum speed (typically 5-10 mph loss) |
| Higher RPM at Cruising | Motor spins faster at same ground speed |
| Reduced Range | Slightly less range per charge |
| Chain Wear | Slightly increased chain wear (use quality chain) |
The top speed reduction is the most noticeable trade-off. If you primarily ride open terrain or want maximum speed, a smaller sprocket (like 54T) may be better. For technical off-road, the 58T’s acceleration benefits outweigh the top speed loss.
Which Sprocket Should You Choose?
Selecting the right sprocket depends on your riding style and weight :
| Rider Profile | Recommended Sprocket | Reasoning |
|---|---|---|
| Light rider (under 75kg) | 54-56T | Balanced acceleration and speed |
| Average rider (75-95kg) | 56-58T | Good torque increase |
| Heavy rider (95-108kg) | 58-60T | Needed for proper acceleration |
| Very heavy rider (over 108kg) | 60-64T | Maximum torque for weight |
| Technical off-road | 58-64T | Slow-speed control |
| Mixed terrain | 54-56T | Balanced performance |
| Street / high speed | 48-52T | Maintain top speed |
The 58T sprocket is the most popular upgrade for the Surron Light Bee . It offers significant torque improvement without excessive top speed loss.
Installation Overview
Installing a 58T sprocket and 112 link chain is a moderate DIY job :
Tools needed :
- Socket set (8mm, 10mm, 12mm)
- Chain breaker tool
- Torque wrench
- Allen keys
Installation steps :
- Remove the rear wheel
- Remove the stock sprocket from the wheel
- Install the new 58T sprocket
- Reinstall the rear wheel
- Remove the old chain (break link if needed)
- Install the new 112-link chain
- Adjust chain tension properly

Complete Sets vs. Individual Components
Two purchasing options are available :
Complete sets (sprocket + chain) :
- Everything you need in one package
- Guaranteed chain length compatibility
- Typically better value
Individual components :
- Mix and match brands
- Choose specific colors
- May need to verify chain length
The complete set from Surron Canada includes both components and is currently discounted to $129.99 (20% off original) .
Maintenance Tips
Proper maintenance extends the life of your sprocket and chain :
- Clean the chain after muddy rides
- Apply chain lube specifically for O-ring chains
- Check tension regularly (25-35mm slack recommended)
- Inspect for wear on sprocket teeth
- Replace as a set when worn
The O-ring design requires less frequent lubrication than standard chains . However, keeping it clean still matters for maximum life.
When to Upgrade Your Sprocket
Consider upgrading to a 58T sprocket if :
| Scenario | Recommendation |
|---|---|
| You ride technical off-road | Essential upgrade |
| You struggle on steep hills | Highly recommended |
| You want better acceleration | Immediate improvement |
| You are a heavier rider (over 200 lbs) | Needed for performance |
| You ride mostly street | Not recommended (loses top speed) |
For trail and mountain riding, the 58T sprocket transforms the bike’s behavior. The stock gearing often feels too tall for proper off-road control. The 58T fixes this.
