Its known fact that the brakes suck on the bandit 1250 and make it worse,,, mine is 1250 abs... All the magazine review, riders here and my experience is brakes suck..
It seems it doesn't matter much, ss lines, new better pads...I got carbone lorraine and it still sucks... bleeding doesn't help... I bled mine and got firmer lever but it got spongy week later... Even with good bleeding and perfect condition... Brakes still don't have the bite and stopping power that are needed.
I don't think its the rotor, pads, ss lines, bleeding.....only option I haven;t tried is the master cyclinder...but at this point its gambling.... suzuki brakes on bandit sucks...
I have old 97 gsxr 6pot brakes on a hawk gt, and it works perfect, almost better then cbr 1000rr monoblocks which I have tried... I also tested ducati monster brembo also..and my gsxr 6pot rivals that and it could be because lighter weight bike...
I don't know why dale holeshot company hasn't address this problem or developed any modification to improve brakes... At this point, I am thinking about selling the bandit and going with FZ1 which has better suspension and brakes but bandit motor is more fun and better IMO,
