ATV Trails Guide: Colorado Central Mountains Book

Without a doubt, the best of the motorcycle instructional books I have read so far, by a considerable margin. The technical description of steering action, mechanics, and geometry are clear, sufficiently detailed, and as far as I (not an expert) can tell, correct! There's a lot of noise around counter-steering out there, but there's none of that here.

My only quibble, and this may be a misinterpretation of the text, is on page 31 of the edition I have where Mr. Parks says:
At these low speeds the motorcycle rides like a bicycle, and you simply point the front tire in the direction you want to go.
which seems to imply that bicycle steering mechanics are different from motorcycle steering mechanics. I am not an expert, but I am convinced the physics is the same for all "tandem multi-wheeled vehicles". You counter-steer a bicycle at speed just as you do a motorcycle.
