Query: Still it is a Great Book!

This is a great book covering a lot of GP bikes from the late 40s to the early 80s. Some I did not even know exist! For example, I always thought that Honda made a 6 cylinder GP bike BUT was surprise that MV actually built one before Honda.However the down side is that the write up is too brief. Pictures are way too little. Each bikes gets only a page and around 3 pictures. It is also missing some GP bikes like the Honda NR500 and the Elf series. These ELF hub steered bikes should well earn a mention in the book even though they are not from any marque.Anyhow it is still a great book!
