mine is from a 2002, the carrier not turning smoothly, there's some resistance, and somewhat crunchy.
pushed bearing out, it's made by NSK (germany), # 6205 B2RSR2NG. the OD is 2.0465-2.0470. the bearing itself turns smoothly and no play.
anyway, since it's 2 years old and over 6k miles, i decided to get a new bearing. JAF 6205RS (made in japan @ $30). same OD as the NSK 6205.
i checked the ID of the carrier, 2.0442-2.0445...
based on the above numbers, the interference is over .002. that's a lot....
that explains why the bearing was tight. the outer raceway was getting crushed causing it to collapse.
we do a lot of press fit bearing installation here and the typical interference is .0005 - .001.
does anyone has an uninstalled oem ktm bearing ? OD?
what's the ID of your carrier?
my next move is machine the ID of the carrier by removing .001 of material.
