I suspect it was the gearing or spindle-size used that caused the problem -
if the alternator was run of a slightly larger spindle, the speed required
would have been reduced in proportion - so it was Laverda's design error,
rather than Bosch's.
I'll bet it was fun trying to keep the headlight going! (I assume we're
talking bikes here, rather than combine harvesters? - I just had this
vision.....)
