my 89 851 was a ron angel imported bike, and it doesn't have a compliance plate either. it was continuously registered in vic from new until i took it off the road in 2005, and it had the number off the plate that's on the frame rail off the lh side of the steering head on the rego papers.
do you have previous rego papers for it? just use that #.
