I'm wondering if this is a good deal. A local is selling a '78 Suzuki DS185 with less than 600 miles on it. Condition looks excellent, really doesn't look like it was ridden much in the picture. He's wanting $600 for it. Now for the bike itself. Was the DS185 known for being a good bike? How was the handling, motor, etc? I can't find much information on it on the net, so it must be pretty rare. Would you grab this up?
