I listen to quite a few podcast during my day. Some as background noise while I work and others while I commute on my motorcycle (Sena SMH10). With the resurgence of classic motorcycles/cafe racers coming back into fashion, replacing the gaudy stretched out affordable choppers. A lot of custom motorcycle shops are producing some wonderful podcasts and or video/photography collections to consume.
One in particular is Stories of Bike.
I came across their website and amazing photos/videos by way of a podcast called The Hold Fast Motors Podcast.
Give them both a try.
