This is my favorite- second owner from new ('72). These "oil in frame" Triumphs get criticized as not being as good as the 70 and older type but the oif frame was inspired by the Trackmaster flat track racing frame and is excellent. At 383 lb this one will leave my Commando wallowing in its wake on a twisty road. One of the last 650's and equipped with 5 speed it's a gem.
