Unintended thread jack.
Seeing as I stumbled into the reading thing again.
Some Motorcycle reference reading suggestions based on my library.
If one wants minimal books, and has fuel injected bike, a good all rounder is Total Control by Lee Parks.
If one wants primary emphasis on suspension and chassis, then Sportbike Suspension Tuning by Andrew Trevitt is good, noting the high quality picture content of the expansive how to.
If one wants more in depth suspension and chassis knowledge, the Suspension for Mortals by Traxxion Dynamics is the way to go. Be sure to get the cheap ancient booklet and not just the current day DVD (2 disc set).
A further supplement to this would be Catalyst Reaction DVDs by Dave Moss, but not instead of. (Dave Moss is the ONLY one that deals with reading tires, and one can get free download info from his website. He does good stuff, but I would not suggest starting with it, and instead, moving into it as further development of one's tuning capability.)
If one has carbs, and/or wants high level presentation of bike tech in general, then Sportbike Performance Handbook 2nd Edition by Kevin Cameron is THE one in my mind.
For road and track riding get yourself a copy of Keith Code's Twist of The Wrist 2 DVD, and the book with the very same title. The DVD is excellent. The book is too, but a bit tedious at times, however the book reinforces and expands upon the DVD and is filled with excellent info and you'll be missing out if you don't get the book too. You can not watch/read them too many times. (Code’s manner of presentation in his books is totally different from anything else you will find. It is not the easiest reading, but is always loaded with really good and authoritative content.) I have all of the Keith Code (California Superbike School) Twist of The Wrist Books, and none of them are what I would call suspension referral text worth looking at from that point of view alone. The Twist of the Wrist II DVD has a sort of suspension section but it is very very weak. Keith’s work is very good on the overall and riding, but forget it on suspension, and note that he does not pretend that his books are suspension guides. They are riding guides, as is the latest DVD.
As for pure track technique, especially if one ends up being a trackaholic or racer of any level, are the two books by Ed Bargy of Ed Bargy Racing Schools. Prime is "Introduction to Motorcycle Road Racing"(where kiss the mirror gets indirectly challenged by the laws of physics presented). Supplemental is "The Complete Anthology of Motorcycle Road Racing Lines".
Sport Riding Techniques by Nick Ienatsch is a very good book, but it is a riding book and not at all a setup book.
Tony Foale's Motorcycle Handling and Chassis Design is a text book and few will appreciate it. BUT new ones of the right issue do have the CD that also has chassis analysis software on it. (that I still have not looked at yet !)
Touring919 suggested Vittore Cossalter’s Motocycle Dynamics to me. I got a copy of the 2nd Edition. This is as serious a text book as is Tony Foale’s. Very few will appreciate it, let alone read it, but if you want more definitive high level engineering and science, get this one also.
