Michael from Denmark would like to know more about the frame he has !
thanks for helping me. I would really like to know which model it is,first the holes has always there.They have not been weld later on.
Thought a BMW R75 engine would fit inside it,from hole to hole is around 33,5 cm.
Where I have my finger is on the steeringhead,is a very littel stamp,se the photo with my drawing number 1.There is not stamped anything on the frame any place as the normal.The frame at the back is a original R71 frame,just for see how close it looks. Where I have my finger at the rearbrake plate, is stamped the things you see on my drawing number 2. The frame is without the reinforcement at the back suspension
