The factory published pretty much the same details for all the bikes on their web pages. There are few differences between the models performance wise, and the only factors likely to have much impact on
performance are cam, Eprom map, the presence or otherwise of the ram air ducts, exhaust system - in particular the collector box, and the type of fairing fitted. The following is therefore a generic specification, originally for the 668 model variant.
