Need suggestion for a video.

I'm looking for background music suggestions for a motorcycle DVD that is made by a friend at a forum I a member at.

As a motorcycle enthusiast he has made a few videos of himself and a friend riding and has upgraded cameras and software with every video and is now getting very good at it...heres a link to pre production clip from his latest offering.

I am sending him a couple of cd's of rock instrumental guitar track that I think might be good but thought who better to ask for additional suggestions than the community here.

Any genre.

Thanks in advance.
