Trusting my memory here:
It is the first of the Italian Huskies. 1988 model, possibly 1989.
They were, as you say, just a rebadged Cagiva. The 125s were the first to be Italianified, because the Swedish 125s were crap in the late 1980s (unlike the Swedish 250cc+ bikes which were still pretty good).
The month on the compliance plate would also be a clue to the exact model, but don't trust it too much from the Euro bikes of that era...
There will probably be a date stamp in the wheel rims, which is another clue.
The Marzocchi "single function fork" (not that they called them that at the time) was regularly criticised for being too soft. I seem to recall there being a problem in getting stiffer single springs, and I assume there's no room for a spring in the dampening leg.
Phil Geilis rode a Cagiva 125 in enduros in 1986 - Same basic bike. There were a few ADB articles on it at the time.
Love to see a photo or ten.
