    Well, to be honest, I don't know;)

    Seriously, there was another springer - the FLSTS - that had the 16" front wheel and I would start from there:
    First, check if part nos for the springer forks are the same. If they are, just see what parts the FLSTS has that yours don't (other than the wheel ;P)

    Ok, I did some of the starting work for you:
    The FLSTS was introduced in '97.
    Your part nos for the springer front as I found are 45569-88B/45607-93 (plus bits & pieces)
    For the '97 FLSTS the nos are 45619-97/45633-97

    This leads me to conclude that this was a new, wider front to fit the 16 x 130mm wheel & tyre (why would they make new parts if the old ones would fit...).
    So, the answer to your question is that IF you're going to fit a 130/90/16 tyre, you'll probably need new springer front but brakes, etc are probably ok.
    Maybe it is possible to fit a 120 or so tyre, but I think the main problem here will be the width of the hub. You need to look & measure carefully to see available space (clearance to disc, caliper, brakets, springer legs, etc.).
    Try to discuss this with some wire wheel manufacturers...
    Good luck, and let us know what you find out.
