There are still many very fine Japanese bicycles available on the used market, and this article is intended as a guide to them. While Japanese bicycles were manufactured to very tight tolerances, and nicely finished (considerably better than their European competition), the Japanese had not yet come to terms with the average American's being taller and heavier than the average Japanese.

This provided a sharper outside corner of each tooth for better chain pickup, and the slant helped the chain slide down sideways into good engagement if it was tending to run along the tops of the teeth.

On a vintage bike in excellent condition (that apparently had a lonely existence in a garage) all of the components likely are original.

In the early '70s, Sun Tour freewheels were a revolutionary development, markedly superior to their European competition (Atom, Cyclo, Everest, Regina etc.) Sun Tour freewheels provided much better shifting than older designs due to the superior design of the sprocket teeth.

The tops of the teeth were not squared flat or grooved, as with older designs, but were asymmetrical, with a slant inward.
