Triumph Bonneville – A Popular Bike in Literature

I recently discovered the fun to be had with Google’s Ngram Viewer.  In simple terms, it allows anyone to graph the relative frequency of words or phrases in all of the millions of books that Google has digitized.  The real fun comes in when we search multiple phrases to get a feel for things like the relative popularity of specific motorcycle makes and models over time.  It looks like the Triumph Bonneville wins again (excepting for a notable spike in Norton Commando popularity from 1970-77).
