The RZV500R was designed exclusively for the Japanese home market and features upgraded parts not found on the standard RD500LC and RZ500 . A major difference is the hand-welded aluminium frame, which is significantly lighter than the steel version used on standard models. The water temperature gauge also doubles as a fuel tank contents gauge at the push of a RHS lever and the front fork preload can be altered from the top of the forks. There is also a red light mounted within the tachometer housing that comes on at the equivalent of 55 mph (Japanese maximum national speed limit). The speedo is of course calibrated in KPH.
The front forks are air assisted with rebound damping adjustment. The rear brake and gear levers are cast from aluminium, as are the clip-on type handle bars. These chassis modifications added up to a weight saving of 20 lb (9.1 kg). The engine was detuned to 64 hp (48 kW) to comply with Japanese legislation. This was achieved by restricting the internal diameter of the exhaust pipes and changes to the carburetor jetting. These restrictions are easily changed to the RD500 specification by opening up the restriction plates in the exhaust to create the same diameter hole as the exhaust pipes had as standard and the re-jetting of the carburetors to suit. The vendor can help carry out this modification if required. The production of the RZV 500 R was limited to 1600 machines and all units were sold out with a week!
This example has only covered 37,381 km or around 23,363 miles from new. The owner reports that everything including the bodywork is original and that the bike starts and runs well.
