I also have an 84RZ and a 75 RD. The RD is a nice bike to ride around town to make noise and spray for mosquitos... The RZ is a nice curvy country bike that loves to be rode hard. Both put a smile on your huge smile on your face. I also have a original looking 74 Z1A. it has my old drag bike engine on it. It ran 5.88 all day long in a dragbike chassis. Fun to catch the ninja boys off guard at the stop lights. dont handle worth a damn though ..lolol
