Yeah, like my owner's manual that says I have 43mm forks and my calipers that say I have 48s. The '02 forks are apparently yet another mid-year change. Out of curiosity, does your bike have the oil-filter-relief frame casting? My '02 and a friend's '02 both have the casting, and also both have 48mm forks.
For reference, the model number for the '02.5 and '03 forks is WP4860. These forks (with varying springs, shims, and valves) are used in several models of bikes. KTM LC4s, RFSs and Husabergs, that I know of.
