Working on a New motorcycle?

Earlier in the week , a long time friend came by the shop while I was working on the latest cafe racer.He commented that I was working on a new bike.
I replied that it was the same one I was working on the past two weeks.
No, he said,what is this a 1980 or 1981 ?
He was right it is a 1981.
Then I started thinking about . If you don't count the occasional service or tires I install,this is a new bike for the shop. Most of the stuff is at least 40 plus years old. The more time I spend with motorcycles the more I find myself drawn to older bikes.
I look over at my future project bikes and the newest model was introduced in 1969 and the oldest model dating back to the mid 50's.
