The crew built and tested a prototype on the trails surrounding Athena.

The all aluminum alloy engine would be based on the two-stroke, piston-port single used in the last Yamaguchi, but with a little more cubic capacity and one more gear, giving it four speeds instead of three. The Cotton made heavy use of triangulation to stiffen the frame, and the PABATCO prototype adopted this idea. Styling cues for the planned bike were taken from the Cotton, a British-made offroad competition machine with a record of success in offroad racing. Rumor has it that much of the initial sketching was done at the local Green Lantern Tavern, with the help of a few cocktails. And with Hodaka already in place to supply engines, they looked to Hodaka to build their new bike. With their most profitable item no longer available, yet with dealers in place and strong demand for small motorcycles, Harry “Hank” Koepke, Adolph Schwartz and other PABATCO employees decided to collaborate in designing a motorcycle for the U.S. The last engine used by Yamaguchi was an 80cc three-speed made by Hodaka, a Japanese builder of two-stroke engines.

But the fierce competition between Japanese motorcycle companies in the early Sixties hit the smaller companies hard, and Yamaguchi went under in 1963. Starting about 1961, PABATCO began importing Yamaguchi motorcycles, first in 49cc and later in 80cc versions, and these proved quite profitable for the Oregon-based company. PABATCO was headquartered in Athena, a little town in northeastern Oregon just north of Pendleton. At the same time, Pacific Basin Trading Company (PABATCO), then a subsidiary of Farm Chemicals of Oregon, was looking to trade Oregon farm products for goods from other countries.

Yamaguchi, one of Japan’s oldest motorcycle companies, with roots back to 1941, was one such company. Following Honda’s success, many Japanese motorcycle companies sought to export their products to the United States.
