Mr Squid has hit the nail on the head again I think... you can't change one, and expect the other to be better - basic levers. If you think the SV's brakes are crap, then it's probably because they're basic floating calipers, as opposed to opposed pistons.

Even so, I've never ever thought that my SV's brakes were rubbish.

you can indeed change both piston size and ratio, you can do this when you buy either a brembo or magura radial mastercylinder. or infact I would imagine any top level mc, they come in all different sizes and finishes, billet or cast, its your choice but then you do pay for it

I thoink I said this in the post-crash version of this thread, but if I did it's gone. I've got a Brembo radial on mine, and I wouldn't dream of going back. True, it's pushing different calipers but it's simply a superior item. The design's better- the vertical banjo prevents air pockets, and it has an integral bleed nipple. It takes the Suzuki brake switch, so no messing around with pressure banjo switches...

The thing is, mine isn't the superbike one- I got it cheap, and it turned out to be the one they sell for a single caliper, 4 or 6 pots. It's a 16mm bore by, I think, 18mm. Now, that's pretty much exactly what the SV is, but the Brembo still works better. It's more linear, whereas the SV one never was for me, even with stainles lines- it was always bit of brake, bit of brake, lot of brake. On the other hand, with the Brembo each bit of movement gives a very linear brake "curve"- bit of brake, bit more brake, yet more brake, lots. This makes fairly little sense from a simple lever engineering point of view, but it works.

It doesn't give me any more power- SV brakes will lock the front in the dry, you don't need more power- but it delivers that power so much better. And it was £50. And it looks ace :) The only thing I'd say is it might not fit well with a curvy fairing- it sticks out further fowards and gave me fits when i first fitted it.
