I have a Kawasaki Estrella 250 motorbike. On the silencer it has " Peyton Place " engraved. Anyone know why ?

The motorbike was imported from Japan to Thailand ( where I live ). I cannot find any link between the motorbike and " Peyton Place " which I remember was an american tv soap. Does anyone know if this was done by the factory or has the motorbike some other significance ? Thanks for your replies.
