My son and I recently picked up a great deal on a running riding 74' Ossa MAR 250. Here we will post as we do the restore on it. The progress will be fast as we hope to have it ready for AHRMA at Donner this July. Now the bulk of the work is going to take place starting in June as we are moving at the end of the month and will start once we get in the new place. We will hit it hard for a month and the bike will be like new when done. I have attached a picture and video on the Ossa as it sat about 2 weeks ago.It runs perfect and sounds great. My son just putting it around for a shake down run. Stay tuned and glad I found this forum.
