On the 24th July 1989 I bought a Donghai SM750, vehicle identification number: 850527609, my first motorbike with sidecar. Emty weight 400 kg of steel. A very interesting motorbike but only a short time of driving it. On my way home from the "Elefantentreffen" in Thurmansbang-Solla suddenly on the highway I lost a big peace of the lower engine housing. Desaster. So only 6 month later I sold the remaings.
