Hi,
I have a spare ZX10R k6/k7 Rear Shock for sale which includes ZX10R linkage and dogbones. It has been taken out of a 9k km (~5600 mile) bike according to the breakers. Quite a rare find these days. As a matter of fact, I had to have it shipped in from Eastern Europe.
£150 ONO for collection in person. I can drop it off within reasonable distance around Derby - Nottingham area.
I can look into shipping cost if there would be any interest in it.
I'll try to answer any questions you might have about it.
