These handle bars are the so called 'jap-style' bars. Used on the lowriders.
Most of them have been bent into this kind of shape.
Do you see any welding marks? If so, the job is done right, and their worth quite a bit.
If not, it's pretty dangerous to ride this way, as they tend to crack.
According to some people, some very very rare Honda's had these type of handle bars, but I'm not too sure about that.
You can buy this shape at G'craft for example, but they do not have the holes for the wiring.
