My first bike was a 1954 R25/3 that I bought when was still living in Germany, back in 1972. Bought it for the equivalent of about $15.00. Rebuilt it without restoring it, kinda wish I had brought it with me when I moved to the US.
Looking forward to watching yours come back to life.
That flywheel is a work of art. Almost a shame to hide it behind the clutch.
Looks great so far.
