Close but not close enough
I have one of your rings on my S2R still looks as good as when it was fitted, and yes everything is plastic except the engine paint which is possibly made of thinned and coloured Stracciatella but doesn't stick as well.
Edit... The lights are appalling, first time out in the dark which was when I picked up the bike I couldn't see where I was going on the dark back roads, well I could but only for about 30 feet ahead which made the ride a bit interesting.
Comparing this to a 40 year old 6V widecase 350 scrambler (my new toy) I'd say they were nearly comparable !!
