The book presents the theory of motorcycle dynamics. It is a technical book for the engineer, student, or technically/mathematically inclined motorcycle enthusiast. Motorcycle Dynamics offers a wealth of information compiled from the most up-to-date research into the behavior and performance of motorcycles. The structure of the book and abundant graphs assist in understanding an exceptionally complicated subject. The book presents a large number of graphs and figures that make the understanding easy.

I find the book by Vittore Cossalter as the ONLY serious and complete reference for the dynamics / kinematics of Motorcycles I have come across. The exposition is very readable and well presented and it has helped me sort out a lot of related issues that I have played around with through own calculations and computer simulations.
I would not recommend the book to people that hate maths as it is full of them (it is a technical book after all as it should be to cover the subject properly) but for anyone whose interests and capabilities go into the realm of motorcycle dynamics I consider it a must have.
I was especially interested in the tyre behaviour analysis (since this was the topic I was most unfamiliar with) but I would rate the whole of the book as top notch.
In a nutshell: If you like that kind of stuff, get it.
After reading numerous books about motorcycling, authored by Keith Code, Lee Parks, David Hough, and Nick Ienatsch, I came across Motorcycle Dynamics written by Vittore Cossalter an Italian professor of applied mechanics. Doing a Google search revealed a whole university curriculum dedicated to the physics and theory behind motorcycles! As a gearhead and licensed professional engineer, I too have a passion for figuring out how things work.
First, I would consider books written by Code and Hough to be excellent foundations for those interested in riding motorcycles. The content is explained in simple layman's terms, with words like counter-steer and pivot steer, lean, and turn dominating the primary activities. With Cossalter's Motorcycle Dynamics, you are dealing more (much more) with the physics and theoretical aspect of motorcycles. Moment of inertia, torque, yaw, roll, angular momentum, gyroscopic effects, torsional stiffness, and a myriad of variables and equations are used to describe the events covered by Hough and Code. So in essence, I consider the books written by Code and Hough to be more of an undergraduate level - important and useful. Cossalter's book is more of a graduate level reading - important, useful, but not very easy to understand or directly apply into the real world without some background in physics, science, or engineering.
As an example, the first 7 chapters of Cossalter's Motorcycle Dynamics models the behavior and characteristics of motorcycles. From kinematics, tires, chassis dynamics, trim, vibration, to stability, it covers the theoretical/actual behavior of motorcycles in great detail with equations and references. The last chapter, Motorcycle Maneuverability and Handling, is what I consider the meat and potatoes of this book. It starts almost immediately discussing topics covered in the "undergraduate" series of books where the effect of wheelbase and trail are related to changes in directional stability. Counter-steering and dynamics testing are discussed in great detail, with graphs showing steering angle and steering torque to describe what happens at speed while taking a turn or entering a slalom.
Some might argue that Cossalter is using 1000 words to describe something that can be said using 5 words. I would disagree, because if you are looking for a Cliff's Notes version of motorcycles, you're in the wrong place. I bought Motorcycle Dynamics because I was curious as to WHY counter-steering is necessary and when it should be applied. Lee Parks did a terrific job of splitting the U-Turn technique from the counter-steering maneuvers, because direct steer is necessary for low speed turns (under say, 5-10 MPH). Parks kept the U-turn section last to prevent any confusion after spending chapters talking about the application of counter-steering.
Cossalter does provide simple relationships between real world events and the theoretical. In one scenario, he described how a rider planned to negotiate a right turn while traveling at a velocity of 20 m/s or about 45 MPH. The rider steers left, and the lateral force generated at the front tire contact point causes a yaw motion to the left, which begins a roll motion to the right. Then he follows up with diagrams and graphs to back up the verbal statements. This makes a lot of sense and inherently describes the science behind what was covered with Hough and Code's texts. It is unlikely the average rider would be interested in Motorcycle Dynamics, but to gearheads and engineers, Cossalter's book is definitely a mandatory purchase for one's library.
Overall: 5/5 stars
