if my memory serves me well, the 02 adventure had a 20mm front wheel axle, and the bearing you have (old) are 26mm - so it looks like the wheel is not the stock one.
The bottom bearing and spacers are the 20mm ones. for bike 2001-2002
some bike in 2003 (sxc) still had the 20mm axle, but other (EXC/Adv) had the axle upgraded to a 26mm
the front wheel, i mean the hub, bearing and seal must be from a 525exc and using a bushing with a 20 mm bore to fit the 640 front fork.
boon boon, measure the bushing od, and if it is 26 mm, then our hunch is right.
if that's the case, you need the bearing and seals for the 525 exc, i have a 2003 (first year model) 525 exc and has 26mm axle.
