Good evening I have just aquired an Ossa with engine number M 340285 but can not find any sign of a frame number it has a white fibreglass tank and a black frame which is not showing any signs of other colours underneath it would be nice to know what model and size motor  cheers

34 is a MK1 Ossa MAR 1972/73 250cc.  The frames weren't stamped with a number on the MK1 they had a sticker on the headstock. The frame has been repainted as they were siver/grey originally

Many thanks for that I can now proceed to change the colour of frame and then riding it

Are you saying you won't ride it until the frame is painted the original colour?
