Here is a list of books I have read so far that I have found to be excellent for any motorcycle rider.
Proficient Motorcycling (should be required reading IMHO beofre anyone gets there lisense)
More Proficient Motorcycling (goes into more detail of the issues discussed in the first book)
Street Strategies (not as much of a book as a reference tool, but it basically points out tons of possible road hazzards/situations and ways to overcome them)
A Twist of the Wrist 2 (great book and you will learn alot about performance riding and the physics behind your bike)
A Twist of the Wrist (not as good as 2 IMHO, and intended more for the racer croud)
