It depends where you are in the world- in New Zealand We knew them as theRZ500 also a couple of points. not actually a V4 engine. They are a 50° staggered tandem twin - actually two RZ 250 engines geared together! . Also the aluminium frame was only in Japan. Most markets got a steel frame from memory.
@@gsxrjeff yes I had one in 85. Pity I still didn’t have it would be worth a fortune! I traded it for one of the first FZ five Valve 750s and I’m pretty sure my RZ it had a silver steel frame to.
