Cheers guys. Now it's just a matter of finding one lol. A m8 has a Harris one I can buy but you have to dent the tank to make it fit! What kind of crazy design is that!
There's some 06/07 ones on fleabay http://www.ebay.co.uk/itm/CBR1000RR-Fireblade-06-07-rear-subframe-Silver-/141598715167 http://www.ebay.co.uk/itm/2007-Honda-CBR-1000-RR-6-Subframe-/191530426887 http://goo.gl/TCc7W2
Cheers dude. I had a search setup on eBay and it didn't get any of those! eBay drives me mad sometimes.
