I bought this book based on this post.

Hadn't spent money on a motorcycle book in a while.
It is very nice and very well written and the pics are great. I will definitely view it as a supplemental book though.
If I was giving a friend advice on what to buy, I would suggest the Ride Like a Pro DVD for low speed maneuvers - it's just a great product, and seeing it happen rather than looking at pictures is miles better IMHO.
And then I'd say get one of the Keith Code or Nick Latchey books about Street Riding - even though they are Sport Bike oriented, they really cover the ride-in-the-curves stuff well.
That said, there are little details in this book that I will take to heart.
And there is a picture of a Valk in the book. On p 155 they have a picture of a guy wiping out on his Harley on the Dragon, and there's an IS in front of him that navigated the curve just fine.

Anybody else have some feedback on good learning sources? I'd like a good DVD on riding in the twisties, one that really "works" like the Ride like a Pro does for low-speed stuff. I bought the Ride Like a Pro "Ride the Dragon" DVD and it was a waste of $$.
