I wanna know that myself. I was told ages ago that the two transmissions are the same. I've never really known if there are any real differences and I thought they should be basically the same although it seems the converter itself might well be different.
I'm glad to read this. I was told frankly, the M/C SS got the BRF just as the GN did. I have read countless times though, the M/C got the CZ and some have said all M/C's except the SS got that, and the SS got the BRF.
