A set of K1, K2-79 or 80-94 hydraulic CT70 forks are tried and true. Not the same style/look as pogos tho.
Fatcaaat rigged a steering damper onto a set of K0 pogos and gave it a big thumbs up. (But then you'd have a steering damper rigged on your front end.)
What is your goal? There are lots of OTHER options, but I don't know of any good ones that maintain the look of a K0 front end.
