The G5 was a mainly European CB250 that shared its frame and styling with the CB360, adding a six-speed gearbox, electric start and a front disc brake to the long-running 249 cc twin. Honda pitched it as a refined sport-tourer, but period group tests found it mild and rather bland next to two-stroke rivals such as the Yamaha RD250 and Kawasaki S1.
