Compatibility and Fitment

The manufacturer lists compatibility with several lightweight electric motorcycle platforms, including selected models from:

• Sur-Ron Light Bee
• Talaria Sting
• E Ride Pro
• Ventus
• 79 Bike

Important: Compatibility depends on the exact motorcycle model, generation, front wheel size, brake system, and fork configuration. Some newer models require a separate brake adapter or additional installation components. The Altis Sigma, for example, may require additional parts rather than a direct installation.

Choose the correct crown and brake adapter for your motorcycle before purchasing. If your bike has been modified, confirm compatibility with the manufacturer or a qualified suspension specialist.

Important Product Information

• Confirm your motorcycle model and model year before ordering.
• Verify whether you need the 19-inch flat-crown or 21-inch drop-crown configuration.
• Check brake rotor and caliper compatibility, including whether an additional adapter is required.
• Select an appropriate spring rate for your weight and riding style.
• Have the fork installed and adjusted by a qualified technician if you are unfamiliar with motorcycle suspension systems.
• Follow the manufacturer’s maintenance recommendations to help maintain suspension performance and service life.

Upgrade your electric dirt bike with the TECH Suspension E39 Fork by Formula and enjoy adjustable, long-travel front suspension engineered for lightweight eMoto riding.
