The Honda S90 was a key part of the company's 1960s US market expansion, slotting between the utilitarian Super Cub and the off-road CT series. Produced from 1964 to 1969, the S90 used a unique pressed-steel 'T-bone' frame and an 89.6cc OHC single-cylinder engine. It offered a sportier riding experience and styling than many of its small-displacement contemporaries, helping solidify Honda's reputation for quality and performance.
Collectors appreciate the S90 for its classic looks, especially the chrome-sided fuel tank and slim profile. Its mechanical simplicity makes it easy to maintain, and a strong enthusiast community ensures good parts availability. They're approachable, fun to ride, and represent a nostalgic period when Japanese motorcycles were becoming mainstream in America.
The market for the S90 is well-established, with an average sale price around $3,600. While running examples can be found for under $2,000, exceptional, low-mileage, or perfectly restored bikes can command prices approaching $10,000. These bikes represent an affordable and manageable entry point into vintage motorcycle collecting.
Buying Tips
- Check the pressed-steel frame and fenders for rust, particularly on the underside and at seams. The chrome on the tank is a key feature, so inspect it for pitting and dents.
- The 90cc engine is durable, but listen for cam chain noise on startup and check for oil leaks around the cylinder head and base gaskets.
- Confirm the 6-volt electrical system is functional. Test the lights, horn, and ignition system, as sorting out old wiring can be a chore.
- Originality is important for value. Look for the correct swept-back exhaust, factory seat, and original grey cables, as many bikes have been fitted with incorrect or aftermarket parts over the years.
Prices range from $1,900 for examples in rider condition to $9,300 for top-tier, concours-level bikes.
