It is lighter because it is thinner - top of chain to bottom, not side to side. This was verified by an actual weighing process done circa a year ago by listmember Harvey Sachs. This was a weighing of the two common types of 1 x 3/16 chains. Not sure how it would come out if you used modern 1/2 inch pitch x 1/8 track chain vs inch pitch.

Yep, you do get fewer gear possibilities, but you just live with it.

And it is of course fitting and proper for a pre-65 or so track bike!
