⚙️ Does Harley-Davidson Use Metric or SAE?
Harley-Davidson primarily uses SAE (Standard American English) measurements — that means inches, feet, and standard fasteners like 1/2", 9/16", etc.
🔩 Tool Types You’ll Need:
- SAE wrenches and sockets: Essential for most bolts and parts.
- Torx bits: Commonly used on newer Harleys for bolts on engine covers, controls, etc.
- Allen (hex) keys: Usually in SAE sizes, not metric.
🧰 What About Metric?
- Some components are metric — especially electrical parts, brakes, and accessories sourced globally.
- On models assembled or sold outside the U.S., you might encounter more metric fasteners.
Conclusion: Most of a Harley-Davidson motorcycle uses SAE hardware, but it’s smart to have a few metric tools on hand — especially for accessories or imported parts.
