Clarendon was a motorcycle built by them from 1901 to 1904. At the same time they also built cars.
This reliable motorcycle was built with the company's own or a proprietary engine, rated at 3hp, in a loop frame. With near equal bore and stroke, it had an extra main bearing, outboard of the drive pulley.
In 1904 there was a mechanical inlet valve, but the marque soon disappeared.
