Maybe its just me, but I have always seen a modern cafe racer in the older F650CS.
This is just a crude Microsoft Paint adaptation. But create a rear fender, get rid of the rails on the "tank", build a proper cafe seat with a "bum stop", some lower handlebars with bar end mirrors, maybe a right design of a cafe "bubble" windshield, and the kinda funky F650CS becomes a more cool F650CR.
Maybe hide the muffler under the rear seat area, with a single outlet centered under the taillight. Or an under engine muffler with a slight chin spoiler. Plus a freer breathing exhaust to give a proper cafe racer bark and this could be a unique cool ride. But, it's gotta be red or black.
