Had to modify the subframe slightly to except the resevoir pot but the fireblade shock has a rearward mounted pot. I understand that there can be an issue with undertray clearance if you run the standard undertray.
You can see more on the members builds section under Project wet Dog
Just to add the CBR shock top and bottom mount width were near indentical , just had to sleeve the top frame mount holes from 12mm to 10mm if i remember right. Shock is 5mm longer than standard but i am running a MC21 17inch rear so all goes back to about standard MC18 geometery.
