Query: Why...

Unfortunately, the author of "Wild Ride" did not take the time to learn anything about motorcycles and exhibits little more knowledge about motorcyclists. From the first page, he tosses out arcane technical observations without knowing the meaning of the terms. Reference after reference is made to both bikes and riders with no regard to substantiation for, had the author cared to verify his material, he would quickly discovered the information he cites is erroneous. I will admit that I did not read the entire book. After the dismay of crawling through the first couple of chapters, I checked random parts of the rest of the material only to discover more of the same. My bookshelf is heavy with books about motorcycling. I have four decades of riding experience, many of those years astride Harley-Davidsons. I know that my reaction to the author's misinformation is not picking at nits, it's an observation of careless journalism. Two thumbs down...
