I know what you mean James about mixing old and new. I like the originals and good restos but sometimes you see a really good interpretation that just really makes it.
I saw recently one the other way round, a modern triumph bonneville but it had a tank-seat unit like one of the Hurricane tridents of the 70's. The unit was layed up in bare carbon with the tank panels in maroon and clear coated over all of it, matching front mudguard as well. it was really well made and justed looked so good but still really subtle.
