If you see a copy of Volume 2 you should buy it. I had an email from John over the weekend and he said that he's out of V2 and it will be a while before more are printed. Powell's in Portland OR has carried both John and Tony's books and might have some on hand so you don't have to order from England (John) or Spain (Tony).
I think you'll like the chapter in Volume 1 on aerodynamics. There's a full page listing the results of about 30 wind tunnel runs on different changes to an LSR bike and I found that very interesting.
Here's John's website:
Broadland Leisure - Publishers of The Racing Motorcycle
and Tony's:
TONY FOALE DESIGNS - Home page
cheers,
