Anybody know if this will work? I have a 2000 426 that now has a damaged swingarm and was thinking of upgrading to the lighter 450 swingarm. I've looked on Yamaha's part's site and see the pivot bolts have different part numbers, but the axel is still the same. I'm sure my wheel will mount up, but not sure about the main pivot or shock linkage. If anyone else has tried this swap, or knows what differences there might be, please let me know.
