Just a quick BEC question, does anybody know if the fitment is the same (i.e. spline and thickness of centre) between 'blade or CBR 1000 and Blackbird?

They look the same to me, but want to be certain before I order anything.

Need a 14t sprocket to fit the blackbird

statement from sprocket adaptors.

Sprocket Adaptors for Fireblade, Yamaha R1, Kawasaki ZX9, ZX10, ZX12, Suzuki GSXR, Hayabusa, ZZR, CBR1000, Super Blackbird etc.

so i would say yes they are the same.
