Which master cylinders after GSXR fork swap?

I am swapping GSXR forks onto my 695 this winter and I was planning to use the Duc coffin-style master cylinders.  I've looked around and I can get GSXR master cylinders for around $200 (brake and clutch).  Since the calipers are Nissin, I see no real advantage to Brembo masters.

The question is: are the GSXR masters worth the $200 or are the Duc coffin-style masters workable?  I plan to get adjustable levers at some point and whichever masters I buy the levers for are the ones I will stay with.

Suggestions and/or advice?  Thanks in advance.

The Duc coffins will work fine, i just changed mine out last winter. But...you will notice a huge improvement with a radial MC.

I am actually using a Yammy R-1 MC (Brembo) currently, because it was cheaper then a Brembo radial. Upgrading your rotors to 320mm will also add to stopping power.

I am not sure if that is a good price for the GSXR master cylinders or not, but i thought the Clutch side MC was a cable?

I'm sort-of hijacking my own thread, but what improvement will I see with a radial master?  Better feel?  More uniform increase in brake pressure with increase in lever pressure?

I know about coffin vs remote reservoir masters, but I don't think that's the improvement that RB is referring to.

A radial master (in theory) will give the rider more feedback when coupled with a radial mounted caliper.  I can say that my pull effort due to the addition of the radial MC has decreased, due to the arrangement of the plunger/piston in relation to the lever(this is the difference between all 'older' style MCs and a Radial MC). ALL my stops/braking is done with one finger.

Hope that helps

Besides the advantages that Cromo's link provides don't forget that if you go to radial masters you'll also get the adjustability factor you don't have with the coffins.
I've been wallowing in my own chaotic and insecure delusions.

The length & power of the lever is in proportion to the sizing of the bore/strke of the M/C, regardless of style or brand. Radials give a better feel with all caliper systems and is a difference most people can feel. A radial caliper improves stiffness (and feel) but at levels that most of us can't appreciate.

I have GSXR forks on my MH900e (same front end as a Monster) and I kept the MH's "remote reservoir" type brembo master cylidners. Seriously powerful brakes. Would be a bit much with a radial pump, imho.
