Not a 54cm. IN 1987, Tempo's came in 21, 23 and 25 inch sizes ( and I think one size smaller and one larger as well, but those are super rare). This appears to be a 23.
And overpriced, although seller is entertaining offers. It is completely original and very little used. Nice bike.
You may want tp look for an 88 or 89, both of which came in 22 inch sizes, closer to the 54 you are looking for. Plus the 89 came with 105 7 speed, still 1050/51 series, a very nice group.
