Do you have any recommended sites or reading?
Following is s copy and paste out of an old thread, with a slight edit re David Moss, plus adding in Vittore Cossalter.
FOR SUSPENSION RELATED READING AND BROWSING
• Andrew Trevitt’s book Sportbike Suspension Tuning is good.
• Lee Parks’s book Total Control (High Performance Street Riding Techniques) has some good content on suspension in various chapters and has a pretty good diagnostics guide in Chapter 15 Suspension Setup. Also see Chapter 18 Chassis Tuning.
• Kevin Cameron’s book Sportbike Performance Handbook 2nd Edition has some good content. This is not a book for you if you want a diagnostics chart, but if you want a deeper understanding of suspension science, it has some excellent content.
• Traxxion (Max McAllistair) has an excellent booklet you can still get called Suspension for Mortals. You won’t find it in a library, so can only buy it from Traxxion. It’s cheap and worth every penny. They superceded the booklet with a 2 DVD set that is really a school session that was recorded. I have them and they are good, but unless you really want to get into it, they are probably more in depth than you want. I believe there are still some booklets left at Traxxion, but they may all be gone by now. If so, too bad, personally I think the booklet with the DVDs makes for a really good combination.
• David Moss’s work is pretty good overall, but be very careful of little snippets out of YouTube segments that can be misleading. For example, there's a short clip that shows how he does a rude and crude quickie setup for track day groups showing up clueless or with whacko settings. But this is NOT at all his clean sheet/do it right approach to front ride height. Another one of his front ride height segments is remiss in that it does not fully present the overall spring rate effect with long top out springs, and how dramatic a change there is when one revises the top out. Overall, good info, but be careful. David is Catalyst Reaction Suspension Tuning. (also see OnTheThrottle.TV) He has two DVDs out, one is An Introduction to Sportbike Suspension(2 DVD set), the other is Twiddling Knobs – Suspension Tuning for Sport Bikes. These are focused primarily on track useage, but have some very good content for street use. David’s work is the only info I have found that has anything on reading tires (in the An Intro’ to ..), some of which you can get for free of his website Feel The Track! Catalyst Reaction Suspension Tuning. Said website has lots of good and free info for downloading.
• Tony Foale’s book Motorcycling Handling and Chassis Design is not a book, it is a textbook. Few will want or be able to use the content. It’s a really good book though, and has some interesting history in it.
Vittore Cossalter's Motorcycle Dynamics 2nd Edition is another serious textbook, same comments hold as for Tony Foale's textbook.
• 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 and it is very very weak. Keith’s work is 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.
I have no websites to suggest, but some very interesting insights can be learned from www shimrestackor.com
I have not looked at Traxxion or RaceTech in ages, but if they are like they were a couple of years ago, they are not educational sites at all.
