I think I see the O/P's point, CF Moto seems to have overlooked assigning an easily referenced handle to it's machines. Owners' own pet names for their rides don't appear to really work as readily identifiable handles for the general public.
"There's a Grizzly, and look, a Commander." "Hey, there's a...Zee-Force?"
A handy brand would be nice but what? Well the styling at least of the Z force is reminiscent of a bird of prey, what with the lines coming to a sort of beak-like point. The birds are pretty much all taken though, and some would just not work. Owl for instance, or worse Buzzard (Lets not even imagine Turkey Vulture)
Osprey would be a bit odd too and I doubt the image of a CF Moto diving head first into the water at high speed is quite the image you want to draw up.
But Falcon might work. Hasn't been used since it was a mediocre Ford compact car in the '60's.
CF Moto Falcon. Yeah. Falcon.
Unless you worry that someone might say, "Hey, look at that Falcon idiot!"
