Arrived from Japan yesterday, it's called "GP500 and MoToGP Racers". It's mostly a picture book with hundreds of extremely clear, well composed photos of the bikes, accompanied with interesting explanations. Like the photo of an Italian vehicle registration sticker (in Jeremy Burgess's name) on Rossi's bike because it's easier to deal with export regulations when a vehicle is registered. Highly recommended. But I can't remember where I bought it from and can't find the email receipt ;-) I will look harder if anyone is interested. Some of it is only in Japanese, but most of it is translated into English as well.
