Timed out loading for me. However, found this: [url=https://www.youtube.com/watch?v=BccQkBB4YUo]The Honda CB750 - 50th Anniversary Open Day
Thanks Cormanus, this is a great article for a person like me who has a limited knowledge of modern day motorcycle history and facts (post 1970) compared to the people participating in this forum. I like the way the article cleared-up the common misconceptions of the terms “sandcast”, “K” vs “K0”
50 years?! Unbelievable!
Thinking back 50 years, in my mind the CB750 is still a modern motorcycle.
Imagine 1976, when I started riding, thinking back 50 years would be around 1926. That would make some serious difference in motorcycling.
My my..... look at all the Rlets.... even on the one on Honda's Museum at the top of the page, and on the original display at the Tokyo show Oct 1968.
I rest my case

I now read the URL. Now I can't stop looking for RLETs!

(I think I am being brain-washed) Nice find Cormanus.
One of the comments to the video said there is going to be another CB750 celebration in June 2019, the weekend after Father's Day, to be held in Ferguson, N.C.
Yeah, some significant 50th anniversaries this year ...
