You mean pgm-fi, I guess?
It just means it's fuel injected, it's not a special edition or anything. The CBR600F had fuel injection from 2001, carbs before that (obviously). It'd be a bit of an effort to change over the fairing on a 99-00 (carb) model, which is the one that had the same body (apart from the front). Could be done, though.
The dash on a fuel injected model has a digital speedo with analogue rev counter, the carb models have both speedo and rev counter as analogue clocks.
