Tuv or full report on the motorcycle

Hello Have a Guzzi team The motorcycle is a Cali II Built. 1984 The Motorrd is registered with a season registration mark, so not signed off. I want to bring the part back on the road Only the Tüv has expired since 5. 2019, because I drove the part 2018 the last time. Now my question: Is it enough if I just have the Tüv made, or I need after such a long time a full report. Greeting Werner
