This was my first BMW, a 800cc RT build in 1979. I bought it in 1989, and found out it used to be an old police bike. It was complete repainted but had still some police stripes colors on the inside of the cover and had the signs of the battery- and radiobox on its rear. The improvised shortened seat was nearly falling apart. I sold it nearly 2 years later when I had an other bike on my mind. I've checked the registration lately; the bike is still on the road.
