The SP was still imported into the UK by Moto Cinelli till 97, this was around the time the company had problems.
You can not be sure what they exported over the pond
Have you any pics of your bike ?, the SP has Ohlins items, 50mm pipes etc
you can also trace the exact model by the frame/engine numbers
if you require further help drop me a U2U I think I have a book at home which lists the frame numbers over the years and this could help identify the model
