Dirt Bikes (Horsepower)

I was very disappointed in this book. It's much smaller and much more basic than I realized. I bought it for my 5 yr old grandson and he already knows way more about dirt bikes than the book outlines. It has very few facts about the bikes themselves.

Terrible pricey for what little content there was. A bunch of silly pictures an nothing more. Perhaps 10 pages in all. Horribly presented and written.
