This was not a production road bike but a privately converted TZ750 road racer. The owner fitted lighting, repainted the bodywork, added silencers and swapped the racing carburettor slides so it could be registered, then struggled through noise tests that it only passed with stuffed pipes. It shows how fierce a detuned race-spec four-cylinder two-stroke was on the street.
