97 to 98 fork tube compatibility
Hey man, I just looked up the parts on Honda's Micro Fiche -- the individual complete fork replacement part numbers are different but the upper tube numbers are the same. The Front Caliper Assemblies for both years are the same part number so they should mount up to either set of forks. The Front axels, hub assemblies, and rotors are all the same too.
The only difference I could find in part numbers was the fork pipe (the lower tube).
I think you should be good to go. If you want to get verbal confirmation please call PJ @hondaeast
