Welcome potratz
The Sport has right side up forms, the SF and CR have upside down forks and the headlight ears are different on the Sport and the SF because of this. The forks are both Olins units and excellent.
The SF and CR have radially mounted Brembos up front.The Sport has standard style Brembos. You can argue that the radially mounted Brembos provide better feedback and control at the margin of controllability. Most users will never approach that point. As you said, you will not be racing the bike.
I believe the SF has black chrome pipes and mufflers. The Sport, and CR have regular chrome.
As far as the engine, and EFI system are concerned there is no difference.
The Sport with right side up forks is actually a more faithful representation of the original Commando.
Also, black and gold is the classic Commando color.
You said your wife likes the black and gold, does she intend to ride with you?
If so, make sure that the Sport is a dual seat version.
Whether you get the Sport or SF, the bike is beautiful. And great fun to ride.
Regards.
