I read it differently, twice.

The main themes of the book are:-
1. Quality; the nature of quality and the philosophy of why it is so difficult to achieve.

2. Education: as practiced in the USA all those years ago and now exported to the UK in more recent times and what an utter lack of quality exists therein.

3. Father-son bonding: covered in various guises throughout the chapters.

4. Motorcycle riding and maintenance: as per the title.

Some years later Persig wrote another book on the theme of morals (without a motorcycle theme as far as I know - I have not managed to read much of that book).

I've read some great books but there's a few in that list that I've never heard of either!

Both Louis books, mondo enduro, Chris scott. Running with the moon is a different bag but I still like it. Nathans book about the trip from Sydney is another good read.

I'd love to get out more but for when I can't books and travel blogs keep me Going:scooter:
