Tech Suspension by Formula – E39 E-Moto Fork | 230mm Travel | For Surron, Talaria, E-Ride Pro & More

Level up your front-end suspension with the Tech Suspension E39 E-Moto Fork by Formula — a high-performance 230mm fork system purpose-built for today’s most capable lightweight electric dirt bikes. Designed and assembled in Tuscany, Italy, the E39 combines motocross-grade hardware with e-moto-specific tuning for unbeatable control, comfort, and confidence on any terrain.

Whether you’re sending big jumps, ripping tight trails, or charging down technical descents, this fork delivers the performance serious riders demand.

🔧 Key Features:

• 230mm of plush travel — ideal for aggressive off-road riding and hard landings

• 39mm hard-chromed alloy stanchions — built for strength, precision, and smooth action

• CNC-machined triple clamp (drop crown included) for rigidity and sleek form factor

• Fully adjustable hydraulics — 32-click rebound / 22-click compression tuning

• Low-friction bushings and HD seals for long-lasting performance

• Anodized aluminum alloy outer tubes and forged lower feet

• Compatible with MTB brakes and Volar Sport Racing Brakes

• Dedicated axle and bushings for plug-and-play fitment with stock hubs

• Fully rebuildable and customizable — performance that grows with you

• Weight: 6.8 kg (complete with axle, crown, and hardware)

• Brake Mount: 220mm standard radial mount

🛠 Spring Rate Tuning:

Every rider is different — that’s why the TECH E39 fork uses swappable coil springs for real customization. It ships with a Medium-rate spring pre-installed, but riders can upgrade or soften the ride with these options:

• Soft Spring (EX-S) – Better small-bump compliance and comfort on tight or technical terrain

• Hard Spring (EX-H) – Firmer setup for bigger jumps, heavier riders, or aggressive MX-style use

Springs sold separately. Installation is quick, and tuning makes a noticeable difference in ride feel.
