97 vs 99 parts fitment

[NoOne65]

I wonder if the front fork assemble sans wheel is a direct bolt on? the new 99 seals are shot but I just changed oil and new seals on my 97. What was the difference in the wheels? I seem to recall something about them was different.

the forks are different internally but all mount points are identical, so you can swap them.

 

Wheels.........early wheels have smaller hubs and bearings.  Later wheels have larger hubs to accommodate larger bearings, and therefore had to have rotors with a different mount circle.  Because the internal bearing diameter is the same, you can swap axles, but you should swap the whole axle and spacer assembly with the wheel. 

 

Same calipers.   You can swap your front end total, or swap the forks and keep your late model wheel with rotors, just swap the wheel, axle, and spacers as a unit.
