What to Inspect Before Buying

These components are durable but expensive to rebuild.

Poor electrical modifications can create future headaches.

Originality vs. Upgrades
Many Airheads have been modified over the years.

- Brake enhancements
- Touring accessories
Quality upgrades can increase reliability and usability.
The key is evaluating whether modifications were performed correctly.
Common Buying Mistakes
Buying the Cheapest Motorcycle
A less expensive motorcycle often becomes the most expensive one after repairs.
Ignoring Maintenance History
Documentation can reveal far more than appearance alone.
Underestimating Restoration Costs
Even simple projects can require significant time and investment.
Focusing Only on Cosmetics
Mechanical condition is generally more important than appearance.
Should You Buy an Airhead?
For riders who enjoy mechanical simplicity, classic design, and motorcycles with character, the answer is often yes.
An Airhead is not the fastest motorcycle you can buy.
It is not the most technologically advanced.
What it offers is something many riders value even more:
A motorcycle that rewards involvement, encourages exploration, and remains enjoyable year after year.
