Has anyone looked into fitting a Nissan or Brembo caliper to the 2012 S or DS FastAce forks?  I've got some calipers about and sure would like to get rid of that POS piece on the bike now.

Lipo423 upgraded his front brakes. It was not a trivial upgrade, unfortunately.

Thanks for the thread....
I would prefer a simple bracket (my calipers of choice are not radial mount) and to keep the current rotor.  I too use regen most of the time and only want the brake when I need it and, when I need it, I really need it   Living in Florida is year round riding while keeping a keen eye out for blue hair.

You might try to locate a set of soft HP brake pads (if such a thing exists) and give that a try first.  The next option would be to attempt to locate a different master cylinder that would apply a greater mechanical advantage, via a smaller actuating piston, to the caliper.  Both of those options would be cheaper and easier than attempting to hang a new caliper on the forks, I would think.

There is a limit to just how much advantage you can put on a poor caliper with a master cylinder before you run into problems with overheating and even seal failure but its certainly a start.  I imagine if you have a collection of smallish calipers you could get one of them to fit without much bother.  It's something i plan to do in the future but don't have access to boxes full of old bike parts to do so.

here is a really off the wall approach....  Sportbike front ends are a dime a dozen.  Has anyone looked at fork diameter and spacing (or simply pivot shaft diameter) for dropping a whole front end on the bike?

That has been done before on more than one model of motorcycle with good results. But that will take some research, good mechanical skill, knowledge about brake systems, front suspensions, etc., along with some luck.  Plus, some of that luck will have to go toward finding a sportbike front end that hasn't been crashed.

You would be better off with a supermoto front end because fastace is an offroad brand and more likely to use that kind of spacing i would think.  Plus they are easy to get hold of because everyone that buys a KTM SMR or similar upgrades to snazzy suspension and wants rid of the old stuff.
