I've had 19 Husabergs, bought back my first one, a -95 FC350, last year.
Had 2 FC501 in -00, with SPES exhausts and vented frontplates, "just" like Smets....
The old bikes turn up from time to time, but they are usually totally destroyed, and parts pre -01 are getting harder to find, just buildt up a -98 FC600 for my boss, with an original Smets frame, 3 speed neutral at the bottom, SPES exhaust etc...
