Kawasaki H1 Mach III listings 3 for sale now
The Kawasaki H1 Mach III shocked the motorcycle world when it debuted in 1969. Its 500cc 2-stroke triple-cylinder engine produced a claimed 60 horsepower, which was a huge number for a sub-400-pound bike. This combination created breathtaking acceleration and a reputation for challenging handling, earning it the nickname "Widowmaker."
Collectors prize the H1 for its raw character and historical significance. It represents a period of unapologetic performance before emissions and noise regulations softened motorcycles. The earliest models, particularly the 1969 version in Peacock Gray, are the most sought-after for their purity of design and notorious performance.
Buying Tips
- Check for the original, stamped exhausts. These are extremely difficult to find, and correct replacements are very expensive.
- The center cylinder is prone to overheating. Listen for odd engine noises and check compression if possible.
- Inspect the frame for cracks, especially around the steering head and swingarm mounts. The bike's power often overwhelmed its chassis.
- Verify matching frame and engine numbers. Many bikes were crashed or had engines swapped over the years.
