Its just a technicality of words... By old terminilogy they were known as motorcycles... but by everything but the 50cc limit sometimes applied to modern mopeds... it IS a moped.
Thats why I am putting them on here... pedals.
And we all get to see the old technology that our grandparents (or great grandparents) saw as the machinery of the day.
I just realized something... I said "the belt needs tightening"... but it doesn't... that long lever that is covering the second 'D' in Davidson... pulls on the other lever... which tightens up that idler pulley in front of the rear wheel... which tightens the belt and makes the bike start to go.
Except the fact that they are worth so much... it would be so cool to ride around on one of these old things.
