Can most brake calipers be altinated between bikes.

There are a set of nice ducati calipers in GOLD on ebay, will they fit??

You can make them fit with adapter plates, but they'd be so strong that you'd find your forks not stiff enough.
I've got a pair of GSXR calipers from a 2000 model, they're easier to fit but with braided lines and HH pads I've got more than enough brakes.

If they stay cheep (i doubt it) i want them just because they look cool, plus they are brembo.

Would they work fine with the current disks?

What do you need the adapter plates for, where do you get them from?

They would work fine with the current disks assuming you made the adapter plates the correct size. You would also need to change your master cylinder as well though.

Do you mean that the brake handle unit would have to be a diffrent one?

Does that mean a new brake handle unit?

A master cylinder of any bike that uses 6 pot calipers should do the trick, think ZX7RR or TL1000R. Of course a nice Brembo radial master cylinder would be ideal but they're costly.

Doesn't need to be from a bike with 6 pot calipers as those Brembos only have 4. Pretty much anything from a modern 600 or above would most likely work.

What's the bore on the original SV m/cyl?

Eh?

Any Brake master cylinder will work with any caliper, but you're unlikley to get the bext outright performance from them. All the master cylinder does is force brake fluid into the system applying pressure behind the pistons, fundametally all master cylinders work the same. Granted if the master cylinder was off a 1 disc 1 pot 125cc bike it would not be up to task but I see no problem here.

Have a look online for adaptor plates or (even better) contact Brembo and ask if:
1) They have a recomended adapter plate
2) if the master cylinder you have will work

What is the mounting size of the SV, is it 65mm or 40mm lug?

No so, if the bore of the M/cyl is too small compared with the bore size and number of pistons in the caliper/s, the lever may well have to great a travel before the pads grip, it may be so great a travel as to not happen before the lever hits the 'bar, it's dependant on how much fluid, (volume), is required to move the pistons a given distance.

How important is the ratio figure, for instance Brembo do a 19 ratio, 18mm bore, and a 16 ratio, 18mm bore. Would a too small a ratio also be inaffective?

The They also do a few more than that. Their 19mm bore can be had with a 20 ratio (for most four pot calliper sports bikes), an 18 ratio (for four pot calliper sports bike with brembo race callipers) and a 16 ratio (for single four pot callipers) and that's before you even consider the 16 ratio stuff.

It's quite a challenge to get the best from your brakes by matching the master cylinder with the rest of the set up.
