nice one ! i remember when they came out ,three of my friends bought gpz,s an 1100 a 100rx and the 900 versions,needless to say my superdream was a laughing stock.
the rx was the fastest production bike at the time and was rated at top speed of 180 mph.although being a pillion passenger doing 140 on the carriageway left me with the shakes!
still a lovely looking bike and i love the noise it makes when you open her up.
i have half a one out my back.....the gpz 500s,always fancied the rx though........lucky beggar :-D
ps my mates took theirs to the autobahn in germany, the only place they could legally thrash them!
