How to Source Discontinued US Harley Parts for European Models

Bringing American Thunder to European Roads

For many motorcycle enthusiasts, the allure of owning a Harley-Davidson goes beyond just the ride; it’s about the experience, the culture, and the individuality. Importing a Harley from the US can provide access to rare models, better prices, and unique custom builds that aren't as readily available in Europe. Whether you're after a limited-edition model or simply want to upgrade your ride, importing a US Harley is possible. However, it doesn’t come without its challenges, especially in fitment, compliance, and sourcing parts for repairs or customizations.

One of the most common hurdles riders face is finding the correct parts for imported US Harleys, especially when those parts are discontinued or obsolete. This is where Legendary Parts comes in — we specialize in sourcing and supplying OEM and aftermarket Harley parts compatible with US models, ensuring European riders can keep their bikes roadworthy and compliant with local regulations.

With our expertise in Harley import parts, fitment upgrades, and legal compliance, Legendary Parts has become the trusted source for riders who want to ensure their US Harley is fully compatible with European roads.

Understanding the Import Process for US Harleys

Customs, Taxes, and Homologation Requirements

To import a Harley from the US to Europe, you must follow a clear step-by-step process: start by purchasing the motorcycle and obtaining all ownership documents, then arrange overseas shipping with the correct transport paperwork. When the bike reaches customs, you need to complete the import declaration, pay the required VAT and duties based on the motorcycle’s value, and provide the shipping documents so the customs office can verify the bike's journey. Once customs clears the import, you can proceed with technical checks and registration in your country.

In addition to customs clearance, homologation is essential. Homologation ensures that the bike meets EU standards for lighting, noise, and emissions. Without proper homologation, a motorcycle may fail inspection when registering it in Europe. Ensuring your US Harley meets these requirements can prevent delays and additional costs.

Required Documents for Import Registration

When registering a Harley, several documents are essential. The most critical is the U.S. Title, which serves as proof of ownership—without a valid, clean Title, neither import nor registration is possible. Vehicles carrying a “salvage” Title cannot be registered anywhere in the EU (a practice that was still allowed in some countries before 2018 but is no longer permitted). You will also need the Certificate of Conformity (COC) to confirm compliance with European standards, as well as the EPA and DOT certificates that verify the motorcycle meets U.S. emissions and safety regulations. An invoice documenting the purchase is also required as part of the registration process.

Having these documents prepared in advance will make the registration process much smoother and faster.

Common Countries of Import

The most common European countries for importing US Harleys include France, Germany, the Netherlands, and Italy.

Poland is the largest importer of Harleys. Many bikes get their EU papers there. It was also possible to import "salvage title" Harleys through Poland in the past, but not anymore.

However, each country has its own specific nuances regarding registration. For example, in Germany, bikes must pass the TÜV inspection, while in France, the DREAL is required. Be sure to familiarize yourself with the regulations in your country before importing a US Harley.

Key Differences Between US and European Harley Models

Lighting and Electrical Systems

One of the key differences between US and European Harleys is the lighting system. US Harley models are built to DOT (Department of Transportation) standards, which differ from the European E-mark standards. This includes different beam patterns, bulb wattages, and reflector designs. To ensure compliance in Europe, US-spec lights must often be replaced with E-marked alternatives to meet European road safety standards.

Speedometer and Instrument Cluster

Another significant difference between US and European Harleys is the speedometer. US bikes typically use MPH (miles per hour), while European models use KPH (kilometers per hour). This means that the speedometer on an imported US Harley may need to be calibrated or replaced to reflect the correct units of measurement. Additionally, odometer conversions may be required to meet European standards.

Exhaust Systems and Emission Compliance

The exhaust systems on US Harleys often fail to meet the strict noise and emissions requirements of Europe, particularly under the Euro 4 and Euro 5 regulations. Many US pipes are louder and lack the necessary catalytic converters required for European compliance. To pass inspection, you’ll need to replace the exhaust mufflers with EU-approved alternatives.

Electrical Connectors and Wiring Harness

Electrical wiring is another area where US and European models differ. The plug connectors for lights, indicators, and other components can vary in size and configuration. For example, rear light wiring and indicator connectors on US bikes may not be compatible with European systems, requiring the use of adapters or modified wiring harnesses.

Common Fitment Issues When Importing a US Harley

License Plate Bracket and Rear Fender

Due to differing license plate size regulations across Europe, US Harleys often have mounting angles and dimensions that do not align with EU requirements. You may need to replace or modify the license plate bracket or rear fender to meet local regulations.

Fuel System and Tank Venting

There are also differences in the fuel venting system. US Harleys are designed to meet EPA (Environmental Protection Agency) standards, which may differ from European regulations. Specifically, tank vent setups and charcoal canisters may need to be adjusted or replaced to meet European standards.

ECM (Electronic Control Module) Settings

ECU tuning is another critical area to consider when importing a US Harley. The US-spec ECM may not be calibrated for European fuel mixtures and emissions standards. You may need to recalibrate the ECU or install a European-compatible ECM to ensure optimal performance.

Essential Upgrades After Importing

Lighting Conversion Kits

One of the first upgrades you should consider is a lighting conversion kit. Full lighting bundles that include E-mark certified headlight, indicators, and tail lights ensure that your bike complies with European lighting standards. These kits are essential for both safety and legality.

Exhaust Replacement

If you plan to ride your US Harley in Europe, replacing the exhaust mufflers is a must. Options like Original muffler, KessTech, Dr. Jekill & Mr. Hyde, and Vance & Hines offer EU-compliant exhaust systems that allow you to enjoy a quieter ride while staying compliant with emissions regulations.

Speedometer Swap or Software Update

To convert your speedometer from MPH to KPH, you can either replace the entire instrument cluster or perform a software update if your system supports it. This upgrade ensures that your speedometer reflects the correct units and is ready for European roads.

Mirror and Indicator Adjustments

Stock mirrors are the same for the EU and the US. Be sure to upgrade your mirrors and indicators to meet these visibility standards.

Legal Tips for Passing Inspection (TÜV, ITV, CT, etc.)

When it comes to periodic inspections, it’s important to ensure your bike meets all local regulations. In France, you’ll need to pass the DREAL, while in Germany, you'll need to pass the TÜV inspection. These inspections typically focus on lights, emissions, noise levels, speedometer accuracy, and VIN verification.
