Formula TECH E39 E-Moto Fork | Sur-Ron, Talaria, E-Ride Pro & More

230mm Travel Front Suspension Upgrade

Italian-built control for hard trail riding, jumps, and lightweight e-moto abuse

The

Formula TECH E39 E-Moto Fork

is a serious front suspension upgrade for riders who are pushing their electric dirt bike harder than the stock fork was built for. Designed and assembled in Tuscany, Italy, the E39 brings together motocross-inspired strength, e-moto-specific tuning, and clean adjustability for Sur-Ron, Talaria, E-Ride Pro, Ventus, RFN, 79Bike, E-Boost, and similar lightweight electric dirt bike platforms.

With

230mm of travel

,

39mm hard-chromed alloy stanchions

, fully adjustable hydraulics, and a CNC-machined drop crown included, this fork is made for riders who want more front-end confidence on rough trails, bigger hits, technical descents, and aggressive off-road riding. The ride feel is smoother, more controlled, and more tunable than most stock MTB-style fork setups found on e-motos.

What makes the E39 stand out is how complete the package is. You get a dedicated axle, spacers, mounting hardware, fork protectors, yokes, and a 30mm CNC drop crown for 21 inch wheel setups. The fork is also fully rebuildable and customizable, so it can be serviced and tuned as your riding style changes.

Spring Rate Tuning

Every rider is different, and the TECH E39 makes spring tuning simple. The fork ships with a

Medium-rate spring installed

, giving most riders a solid all-around setup right out of the box. For riders who want a softer or firmer feel, optional coil springs are available separately.

Soft Spring EX-S:

Better small-bump comfort and traction for tighter trails or technical terrain

Hard Spring EX-H:

Firmer support for bigger jumps, heavier riders, and more aggressive MX-style riding

Springs are sold separately. Swapping spring rate can make a big difference in how planted the front end feels, especially if your stock fork dives too much, feels harsh, or does not match your weight and riding style.

Final Word

The

Formula TECH E39 Fork

is one of the most capable suspension upgrades available for the new generation of lightweight electric dirt bikes. It gives you real travel, real adjustability, stronger hardware, and a more planted front end without jumping into an overcomplicated custom front-end build.

Do not forget to add headset bearings if your bike needs them. These forks do not include bearings, and starting with fresh bearings is the best way to keep the install clean and the steering smooth.
