I thought long and hard about this topic
I've got a CB750 with a bunch of new parts.
but then I got a screaming deal on a CB900SF
AKA 919 or Hornet 900
Most of the style of the old bikes, in a new easy to deal with modern package.
I'm still trying to figure out a number 19 style paint scheme.
(But I did keep the old CB just because I like these bikes so much.)
