The late K-series CB250 was the Western-styled successor to the tall, slim CB72, carrying on with the 56 x 50.6 mm SOHC parallel twin and five-speed gearbox. It was heavier than earlier Honda 250s without gaining power, so it was no faster, but it earned a reputation as a dependable, economical commuter. The K3 and K4 updates of the early 1970s were largely cosmetic before the bike was replaced by the six-speed G5.
