only difference in any of the cr/sp/fe models is mainly the body work, ie, carbon parts over plastic and a oil temp gauge.
everything else was the same from model to model, in short.
nothing special about them....

SP models had aluminum swing arm, wider rear wheel/tire, Showa suspension (some CR's had Marzocchi non-adjustable forks) and a few other bits. Best bang for the buck (carb wise) is 41 mm FCR's on Malossi short stacks.
