I just added RC calipers (on an otherwise stock system), and they don't feel much better to me....maybe very slightly stronger if at all. They're still a bit spongy, and I can still pull the lever to the bar (standing still only). My Hawk GT's lever won't pull to the bar no matter how hard I pull.
I'm thinking it's air, but they're pulling airless through the Speedbleeders. They're not unsafe to ride on, just annoying. I was expecting better from the new calipers?!?

The issue is pumping your master cylinder to bleed the system. Whereas Greg may disagree, I know from experieince pumping the MC strokes the piston into the bottom of the cylinder bore where all sorts of nasty crud lives not normally visited. This crud and possibly oxidation can tear the o-rings on the piston with bad results
we had a run on this issue when I was at honda, new techs would come in and do a brake job and we would have to replace the mc cause they did not know they would kill them if they over extended (went beyond normal application) when bleeding the system. the mighty vac or a air assisted power bleed system is well worth the money

I have a 929 front end on my SHawk with 954 calipers, EBC wave rotors, EBC sintered pads, Braking stainless lines , and a stock master cylinder. Stops very well. My question is will the gsxr 6 pots work on the 929 front end? And If I just swapped out the stock master to a 07 gsxr master would that make a significant improvement?

I do not think you can us the VTR lever. Have you bought these parts yet? bare in mind, with the 600RR (and many others) you may need to grind (a dremel with a small sander "drum" works well) or mill a relief to clear the VTR fork lower caliper bracket. Do a search and you'll see. I wanted the larger matched pistons the 01 RC51 MC & F4i caliper combo offered, and with new pads bedded-in after 400 miles it now stops about 35~40% harder than the OE setup. This is in addition to the braided lines I already had.

The stock VTR front brake lever pivots on a much shorter bolt than the 03 CRB600RR front brake lever. The stock lever is too thin to work properly. You've got to get a replacement lever.
I tried 954 calipers and the stock MC. The brakes felt mushy and the lever had a lot of travel, The change to an 03 CBR600rr MC firms up the brakes and provides better feel.

thanks skokievtr & comedo...I haven't bought them yet but will be looking to pick them up in the next few days from the guy (depends on schedules). just wanted to make sure of what all I needed. I knew I'd have to grind a bit and that's not a problem.

looks like the lever comes with it afterall...just found the ad for it tonight locally so we'll see how this goes.. I guess i need to figure out now if the pads I'm buying from you skokievtr will work on the 600RR calipers

New to this forum, from Australia, doing the GSXR 6 pots
Hi Guys,
Jack from Australia.
I have read this link with great interest and I am just starting this type of mod.
I'll be using 2001 (K1) GSXR1000 calipers, cause I think they look great, they have incredible power, and getting RC51 stuff in Australia is like finding rockinghorse ****. But GSXR1000 are common (enough)
I have a GSXR1000 master cylinder as well, as it seemed logical to use the one matched to the calipers, bit not 100% sure of the fit yet. If it doesnt go well, I'll get the 954 M/C.
The calipers cost be $200AUST and the M/C $50AUST, and I already have S/S braided lines. The prices probably sound pricy to you, but everything here is more expensive (New VTR100, 05 model = $14990AUST [which is $14100US) and petrol is currently $1.60AUST per litre = $6.10US per gallon)
I'll post pictures and descriptions as I go.

WELCOME to the forum,
Yes it will fit, many have done it. I inverted and reversed the silver m/c reservoir bracket for better clearance. This will make more sense when you bolt thing on. I also need a couple of washers on the caliper mounts to center them on the rotors.
You'll need to use a gixxer brake lever, of course, but I did grind down the VTR lever and made it fit. I only did this because the used gixxer lever was heavily damaged and so the levers would match in look and feel.

Never mind, I found an online parts micro fiche which showed the part numbers as similar but they look quite a bit different. I thought they might be the same since they are both 6 pot calipers until the Gsxr1K went to the radial mounts.

Thread resurrect!!!
So what is the better option? F4i brakes milled to fit, or 6pot GSXR 1000 brakes swapped in? Each with either their own MC or the stock VTR one depending on which is better again.
edit: the F4i are much cheaper, but that isn't really the question.

I've had both on my bike and they both felt like they had the same stopping power. I ended up sticking with the F4i setup because it kept a stock look for my bike. The F4i setup I had (F4i M/C, Steel Braided Lines, F4i Calipers) also has a much better lever feel than the GSXR setup I had (CBR954 M/C, Steel Braided Lines, GSXR1000K1 Calipers). No matter how much I bled up the GSXR setup it never had a good feel. I imagine this was because the "hydraulic ratio" was not correct. I ended giving the setup to my buddy who absolutely loves it.
