Looking for a better front master cylinder ? than the 06/07 GSXR 750 that I have now......

So I've got a 2005 SV650 that I ride in Advanced group. I have the complete front end from a 2006/2007 GSXR 750 on it and I am not real happy with the front brake lever travel / feel. Other than regular bleeding with Motul RBF 600 fluid and EBC HH pads its all stock OEM stuff. Calipers are clean as a whistle. And as far as I know it is the new " after recall " master cylinder.

The biggest thing that I dislike is that for my preference, the lever travels too far even with the adjustable lever all the way out ( away from the bar ). I prefer to pull the lever about a 1/2 and I want a rock hard lever at that point. Mine has a pretty decent solid feel BUT it's not until the lever gets way too close to the grip for my liking.
I just did a track day at Road America on Memorial Day with the fresh pads and fluid and by the end of the day the lever was getting even closer to the grip also. A good bleed will generally fix the issue of the lever getting even closer to the grip and its good again for next time.

Now in comparison, I also have a 2006 GSXR 1000 turbo grudge/drag bike and the lever travels too far on it for my liking also, but I can deal with it on the strip, I don't use the brakes nearly as much.

So is this just a common trait of the GSXR front master cylinders or what ?

Another comparison is that my wife has a 2013 Ninja 300 she tracks, and a 2009 FZ1 she rides and BOTH of them have MUCH LESS lever travel than the GSXR (s) and a really nice rock solid feel to them. I would think the GSXR would be quite better than either of those bikes but nope.

So I really don't know if I'm having some other issues ( but both my GSXRs seem the same ) and I really dont recall how the OEM SV brakes felt in comparison, but I don't recall having this excessive lever travel like the GSXR setup does.

So the question is, after having done some searching, it seems as a front master from an R6 ( Brembo ? ) is a popular swap.
Will that take care of my excessive lever travel issues I'm having ?
And is the R6 master a simple swap / replacement as far as the line size/setup and everything else goes ?
Any other info / advice to correct this issue is appreciated, and sorry this got so lengthy.

 

The EBC HH pads are the worlds worst brake pads, ever.

You didn't mention if you were using aftermarket brake lines or not?

Here's how to remedy your issues:

Buy this......https://store.hardracing.com/acc-cy...-cylinder-w-fixed-lever-rst.html?category_id=

and then these.....https://www.ebay.com/itm/09-10-11-2...XR1000&hash=item4b68bf3e29:g:JKMAAOSwsU5dTPvI

don't forget these.....https://www.partsgiant.com/p342065-...ad-race-brake-pads?r=mg-25&r=c-23176&f=114446

and in case you don't have aftermarket brake lines.....https://www.revzilla.com/motorcycle/galfer-superbike-brake-line-suzuki-gsxr-1000-2009-2011

You're good on the RBF fluid.....

You'll never have brake issues again with this setup.

 

+1 on the HH being sub par... those are street pads.
You could swap a whole R6 radial setup pretty easy. You can source some spacers from Zoran . https://www.twfracing.com/PartsPages/R6caliperspacers.html
A set of pads would be ~$120ish... unless the calipers you got had decent pads already hung. stickboy sells DPs or KurveyGirl has vesrahs Pads are like oil so youre on your own to figure out what kind of
feel youre looking for.
All in could be done for <$300 with new lines and all.

 

There has been a recall on many gsxr master cylinders... for years now
But even with the repositioned bleeder, the performance can be hit or miss.

I went with brembo MC and have been a happy camper. The billet is noticeably better than the RCS. I find the rcs a little vague and the pull a little longer before the bite point. I skipped over the cast racing MC, but imagine it is fine as well.

A good MC has been the biggest change along with vesrah srjl xx pads. And stainless steel lines to replace the stock rubber lines of course

 

I second this. I’ve had the material from a pair of front EBC pads fall off the backing plate on a new set while heading out on track. Thank god out of dumb luck it happened in pit lane

 

Thanks for all the replies and info guys
