I have had a '70 Honda CL350, '79 Honda CB750, '74 Honda CB 450, and a '69 honda s90. They were all a joy to work on and ride, and you could still get parts easily for them. I'm sure they were all smoother than a Harley too.

I've since sold them all except the s90 due to concerns about being smashed by morons in SUVs talking on cell phones.
