I read somewhere the late model BFs have the same bottom end as the typhoons? not sure Few interior changes mentioned... really minor ones... more silver bits etc, and in BF the clock pod.. and Bfs have that stability thing that my BA doesnt... theres also something different about the thermo fans / radiator set up, fins on either side of it that divert air differently, or something.. I read it on here... ive only got the BA II though... not sure of much... The BF bar looks better... like the one in the header.. BA bar is VT styled
