So... I have read that braided lines won't make any difference to an ABS blade, because of course it is a brake by wire system, so in theory the pressure applied from the lever is managed solely by the pump. Makes sense. Well, I threw caution to the wind and got a set of HEL braided lines and coupled them with some Brembo M4's... and guess what. They feel a lot sharper than they did before. And before anyone says it could be because of the bleed - I've had the brake fluids changed twice since ownership and they remainded the same. But this time around the bike feels sharper on the brakes - noticeably sharper. And I don't think that the M4's are the reason. Anyway, that is all I wanted to say . I just wanted to say that if anyone does want to add braided lines to their ABS equipped blade, they will notice a difference.
I fitted braided lines and a Brembo MCS to Danny's ABS Fireblade SP over the winter.. and he says a massive difference..
