I think most motorcycles makes use of a magneto, rather than an alternator.
Not sure what the tech behind the magneto is though.
The magneto is the gray circle at the front of the engine, if I remember correctly the points were under there?.
A little before my time there Nigel, but I had a couple of field bikes that had magnetos. The magneto was driven from the flywheel, attached directly to the crankshaft. The point set was operated from a cam on the inside of the flywheel and thus, was a bit of a bugger to set the gap through the flywheel window.
The alternator coils are under the flywheel as well, usually two, one for charging the battery, and the other for directly feeding the headlights.
In that case the headlight circuit is also AC
The same happens (or used to happen some 40 years ago) in some bicycles: the generator had a rotating permanent magnet and a fixed coil. It fed the headlight and a small taillight.
It was known as the bicycle "dinamo", but in fact it was an alternator and not a dinamo as dinamo means DC generator.
