My wife had a 1973 Yamaha 250 RD back in the 70's when we first started dating. The bike in the pic is just a copied image. I had stripped off the paint and painted the tank and covers Pearl white and yellow. It was a blast to ride.
I also had the same bike brand new , my very first bike .i was 16 and rode it to work ,exactly 40 years ago and then I had its big brother a Dt 360 a green bike the same as Hanso.they were good trail bikes to ride along bush tracks , always reliable ,then onto the triumph pre-units late 50,s early 60 models
Nolton, there is a salvage yard with piles of those old bikes in Mena, Ark. It's just north of town. I believe it is called Intermountain Cycle tel479)394-6746.
