Not sure about the dark part in the top, maybe I should cut it off?

Anything else good/bad?

This is a super photograph. To make it jump, zoom in a bit to cut the out the black at the top (as you mentioned), loose as much of the bike on the left ( showing just the very front of the bike) and then crop up the bottom at the edge of the fuzzy forground. Try it and then let your tastes tell you how much of what.

Beautiful action shot. My only comment is that I prefer to see the motorist on the left side not cropped by half. Congrats.

i would actually darken the top part, probably via global contrast bump, to add a bit more tension to the photo.
