Honda Dream 50 (AC15-1007336). DOHC 4-stroke 50cc with gear-driven cams
Very good condition with negligible wear. Does have some deterioration in the finish on the triple clamp and some rust in the tank.
Runs and rides well.
While not inexpensive when new, these were popular in Japan. In our buying trips we’ve seen examples with up to ~50k kilometers. That’s a pretty usable 50 and a testament to the solid design, high quality and serviceability.
