I'm going to change the rear spring and possibly the shock, has anyone tried this yet because looking at it it would seem that you need to remove the swing arm to get it out.
Yes I have removed mine, you do NOT need to remove the swing-arm but its a bit fiddly to get it out. This is what I did:
1) Jack up bike
2) Undo bottom suspension links.
3) Remove Preload adjuster knob from shock.
4) undo top shock bolt.
5) Lift the swing-arm and the shock can be twisted and got out.
Not for 5 you really need 2 people, the shock has to be twisted to get it out.
