Tech E39 Fork Review: Why It's the Best Suspension Upgrade for E-Moto Riders
Upgrade your ride with a suspension built specifically for today's high-performance electric dirt bikes.
When it comes to upgrading an electric dirt bike, few components make as dramatic of a difference as the front suspension. More power, larger jumps, higher speeds, and rougher terrain have pushed many stock forks beyond their limits. That's exactly why the Tech E39 Fork was developed.
Unlike many suspension options adapted from mountain bikes, the Tech E39 is a true powersports suspension system engineered specifically for modern electric motorcycles. Whether you ride a Surron Light Bee, E Ride Pro, Ventus, Rerode, Talaria, or 79 Bike, the E39 delivers the stiffness, control, and confidence serious riders demand.
Built for E-Motos — Not Mountain Bikes
One of the biggest differences between the Tech E39 and many competing forks is its design philosophy.
Instead of modifying a downhill mountain bike fork to survive the increasing performance of electric motorcycles, the E39 starts with a motorcycle-inspired platform that has been refined specifically for e-moto use.
The result is a fork that feels planted, predictable, and confidence inspiring whether you're charging through whoops, blasting motocross tracks, or hitting technical singletrack.
More Travel Means More Capability
The Tech E39 features:
- 39mm chromoly stanchion tubes
- 230mm of suspension travel
- 770mm overall length
- Dual spring design
- Dual damping cartridges
- Compression and rebound adjustment in both fork legs
With 230mm of travel, the E39 offers over an inch more suspension travel than many common e-moto forks. That extra travel provides:
- Better bottom-out resistance
- More comfort over rough terrain
- Increased confidence on jumps
- Improved front-end stability
The slightly taller design also helps level many bikes that sit low in the front from the factory, making it an excellent match for riders running 19/16 or 21/18 wheel setups.
Real Motorcycle Suspension Performance
Many stock e-moto forks use a spring in one leg and a damper in the other.
The Tech E39 takes the proven motorcycle approach instead:
- Spring in both fork legs
- Damper in both fork legs
- Balanced load distribution
- More consistent damping
- Improved stability under aggressive riding
Instead of forcing one fork leg to do all the work, both sides share the load, resulting in a much more controlled ride—especially under hard braking, rough landings, and repeated impacts.
Incredible Front-End Rigidity
One of the first things riders notice is how solid the front end feels.
During testing, riders consistently described the Tech E39 as feeling much closer to a full-size motocross bike than a traditional electric dirt bike. The increased rigidity virtually eliminates unwanted fork flex while giving riders significantly more confidence in corners, jumps, and high-speed terrain.
For aggressive riders, this translates directly into:
- Better steering precision
- Improved cornering confidence
- Greater stability through braking bumps
- More control at higher speeds
Durable Chromoly Construction
The Tech E39 doesn't just ride better—it is built to last.
Instead of aluminum stanchions commonly found on many e-moto forks, the E39 uses chromoly steel stanchion tubes.
Chromoly offers several advantages:
- Exceptional durability
- Excellent scratch resistance
- Lower friction against fork seals
- Reduced stiction
- Longer service life
Lower stiction means the fork reacts more smoothly to small bumps, roots, and rocks while maintaining excellent support during larger impacts.
Fully Adjustable for Every Rider
No two riders are alike.
The Tech E39 provides extensive tuning options to match your riding style.
External Adjustments
- 32-click rebound adjustment
- 22-click compression adjustment
- Independent adjustment on both fork legs
This allows riders to dial in suspension performance for:
- Motocross
- Hard enduro
- Trail riding
- Desert riding
- Racing
- Freestyle
Easily Tunable Spring Rates
Every Tech E39 ships with medium springs installed, but riders can customize performance even further.
Available spring options include:
- Soft
- Medium
- Hard
Since each fork leg has its own spring, riders can even mix spring rates—for example, running a medium spring in one leg and a hard spring in the other to create an intermediate setup. This provides up to five effective spring combinations for dialing in the perfect feel.
Open Bath Design Makes Maintenance Easy
The Tech E39 uses an open bath damping system, offering several advantages:
- Easier servicing
- Simple oil changes
- Quick spring swaps
- Straightforward tuning
- Lower maintenance costs
Unlike more complex closed-cartridge systems, an open bath design is easier to work on without sacrificing excellent performance for most riders.
Purpose-Built Geometry
Unlike oversized motocross conversions that often require thousands of dollars in additional parts and custom fabrication, the Tech E39 was designed specifically around the geometry of electric dirt bikes.
Traditional KTM 85 fork conversions often require:
- Custom triple clamps
- Geometry corrections
- Rear suspension modifications
- Extensive setup work
- Significant expense
The Tech E39 achieves comparable performance while remaining a bolt-on solution that preserves proper handling characteristics.
Compatible with Today's Most Popular E-Motos
The Tech E39 is an excellent upgrade for riders looking to maximize suspension performance on bikes including:
- Surron Light Bee
- E Ride Pro
- Talaria
- Ventus
- Rerode
- 79 Bike
- Other first-generation e-moto platforms
Adapter kits are also available or planned for many newer-generation models with updated brake systems, making the platform highly adaptable as the e-moto industry continues to evolve.
