Looks almost identical to my '79, except for the dual disc brakes, Comstar rims, and the mufflers -- are they aftermarket? The paint is the same as my factory '79 K model. Are you sure this bike has not been altered? Don't get me wrong, it is one beautiful bike! I love my '79, and it has taken my wife and I on many a trip, and a few tours (1,935 miles circling Lake Superior, from our house, in 2009!). I will always be a huge fan of Honda's CB750K's... Cheers!
