Would you consider this as "normal behaviour" for this lens?[/quote]
Yes, a rather huge amount of CA and also Purple fringing is common with ultra fast primes.
In your sample, I'm not sure if this is fringing or simply "normal" LoCAs. I have the feeling the focus is a tad behind the bike. This would explain the magenta casts in front of the focal plane.
At very large apertures, it's rather difficult to find a subject flat enough to completely fit into the thin DOF.
However, I must admit that NX2 did a remarkable job in removing the magenta casts.

Besides that on DX I have the impression that the borders a pretty good.[/quote]
They are a bit better, yes. A DX review is coming, too (both in Canon and Nikon mount).
