Ok, for anyone who wants to change their 98-99 swing arm to a 03 model you better make sure your dedicated to the tasks at hand. I had to ream out the frame on both sides because the holes are smaller on the 98, the 03 bolt is much bigger. You can use an 03 shock on the 98 also. The 98 swing arm has a smaller opening for the rear axle so you wont be able to use your stock wheel because the bearings are too small and smaller bolt/ bearings on the pivot shaft. I did the swap so i could use the 6.0 wheel from an 03 and plus the newer swing arm is allot stronger. Another note on the 98-99 is that the steering head is bigger on top and a 02-03 triple will not work because it uses a smaller top bearing. . You can use the forks on a 98-99 model from an 03 but you will need the brakes and wheel also becase the 98-99 axle is smaller. The fairings all inter change from 98-03 except the tail section. Tail light is the same, motors all bolt in from 98-03 also.

Here is a look at the bike with the new swing arm. Will post more pics when it is all together.

 

Hello to all, I have a 1987 fzr1000 genesis, i want to fit my 89 exup swing arm, does anyone out there happen to know the serial or part number of the bearings i need to this?

 

You could hit up your bearing specialist. Or even compare the fiches.

 

I am not sure if yamaha has a parts diagram and part # listing diagram like the Kawi site does but a dealer could possibly give you the part #s. You could also try a forum for just yamaha bikes.
