A different guy said said:
"I had to make some spacers, cut some of the VFR Spacers and trim the VFR Swing arm to fit around my engine. Maybe an hour and half total machine time.
Some things that made it easy. The shock linkage mount on the the swing arm is in the same spot as the 954
(left to right not forward to rearward). I had to use the dog bone from the VFR and turn my Triangle linkage plates 120 degrees forward.
The length of the VFR swing arm is the same as the 954
so i was able to use my original chain. The VFR used a 43 tooth rear sprocket same as the 954
so my speedo stayed the same. My ride height is exactly the same as it was before so i didn't have to do anything with the kick stand.
Overall it was a perfect fit."
Here's his pics:
Step one - Remove Seals and bushing, Cut 1/4" down both sides.
Step two - Clean edges up with a file
Step 3 - Clean and re-insert seal and bushing (The Bushing will have to be trimmed too but this will be part of the fitment stage of the swingarm)
I used the stock 954
pivot bolt. I drilled the inside of out so that the VFR pivot bolt can go through it. I then cut the head and the threads off the 954
hallowed out pivot bolt and used that as my spacer between the engine case and the VFR pivot bolt.
As for more machine work , I had to make custom spacers. and that was it.
