A friend of mine is looking to restore a '74 Honda CR125M to concourse condition, but it seems difficult to find a set of cases with the engine number still intact or without damage caused by the chain derailing. Anyone out there with a set of good cases, a complete motor, or even a complete bike to restore with good cases. May even consider a concourse condition bike already done, as sometimes it works out cheaper and a lot easier to buy a bike with all the hard work already done.
