Look at the beautiful Brembo monoblocks now offered on the 2011 GSXR 600 & 750!!! Any chance in hell they will fit '04+ Gixxer's just by looking at the mounting point on the fork bottom? Dammit I sure hope so!! http://www.motorcycle.com/gallery/g...l?g2_GALLERYSID=TMP_SESSION_ID_DI_NOISSES_PMT
The only way to know right now would be to pull up the specs on those calipers and see if they match the measurements. If not you might be able to use a combo of spacers like how they fit the R1/R6 monoblocks on the GSX-R's. I have a 09' 750 that I want to put the '11's calipers on so I'm waiting to hear myself.
I read somewhere that the bolt spacing is 108mm so that should mean they'll bolt up but not sure about the offset.
The offset is determined by the fork bottoms, not the caliper. Basically all 108mm calipers are interchangeable. Bear in mind that these calipers are not the same as the regular Brembo M4 cast monoblock that they sell, or come OEM on the new Ducati/Aprilia/MVs. These calipers are 32mm x 2, the aforementioned Brembo M4s are 34mm x 2. For comparison the stock Tokicos they replaced are 34mm and 30mm pistons.
Backup? Do you know for sure they are 108mm's? As far as not being the same monoblocks as the Ducati etc. I completely understand but cast Brembo MC's most of us use aren't "like" the forged WSB offerings etc. and are still a HUGE improvement over stock.
That's not what I meant.....the design of the caliper is the same. What I said is the ones that come on the GSXR have 2mm smaller pistons than what comes on the Duc. 34mm vs 32mm
so what are the diameter of the pistons on the R6 calipers? and I have a feeling there wont be too many cheap ones of these on the market for a while...
So how do the R1/R6 calipers improve breaking if the pistons are smaller? Isnt it a case of larger piston more breaking power?
