If you've got an iPod and are interested in Podcasts then you might be interested in the MotoGPod, which is a weekly audio magazine on MotoGP scene. I've been listening for a few weeks and you can get some interesting insights and gossip as well as good dialog. 20-40 min episodes, good for train rides, traffic jams etc etc.
Access either at
http://www.MotoGPod.com or open iTunes and goto the Music Store ... Podcasts and search for Motorcycle.
Think of radio 4 meets an american Micheal Scott.
