Rumour was that the SR stood for 'STATESIDE REPLICA' and this was what Kawasaki thought a replica should be!. It was basically a C3 with slightly 'chopper' styling. Chrome plating was used on the headlamp shell, clock lowers and chain guard. The rear tailpiece was dropped in place of a painted rear fender. The front exhaust downpipes were crossed over and the mufflers were made a bit shorter. Only one color was offered in the UK, midnight blue which was really a purple color although other countries got a red version as well. The rear wheel was now a small but fat 16-inch item for that all-important custom look. In America there was also a D1 in 1978 and an E model, which were very similar but did not have as much equipment.
