Not KL, imo. That is nearly 5.5 pounds frame + fork, in a medium size. Too heavy. Seat post should also be 27.4 for KL. Two big strikes....
I have a 61 cm. 1980s KL TT frameset. Right around 2400 grams, bare frame + fork. (Just weighed it, with headset and both brake calipers attached, at 2800).
Your frameset is most likely SL, I would say. Could be a mix of SL and KL, though, perhaps? Does it have a legit KL tubing decal?
The published weight difference between a KL tubeset and an SL one was about 250 grams. (1675 vs. 1925, probably a 'small' set?).
