Has anyone tried or do you think a smaller round cup sized front master cylinder would work on the R3 ??? Maybe from an R6 or something similar ???

I see the stock master cylinder causes a lot of interference with after market clip ons, plus it is DOG UGLY and looks ancient !!!

Thanks...

13mm piston for 2 pots. 16mm if you go 4-pot or dual 2-pot caliper. 18mm if you have dual 4-pots.
I posted somewhere in the Braking board about this. Unless this thread evolves into an actual HOWTO I expect it'll get moved by the mods.

I bought a m/c brake/ clutch lever kit off eBay that my ninja 2-fitty buddy bought. His levers and brake feel are awesome. I'll try later to post where I bought them from.

Do you already have SS lines? I felt the brakes felt extremely mushy but I didnt want to spend too much time or money modding (I get too carried away) on a bike I am selling in 3 months.

Bought a SS line from Jesse, and the mushiness has gone away. It still doesnt stop as fast as I would like for it, but the bike also only has 200ish miles, barely enough to say the pads have been bedded in. I think the next step would be new pads, but we will see .

I don't have SS lines yet, but they ARE on my list. My ninja buddy is a street only rider and has stock rubber lines and the eBay m/c and levers, and his brake lever feel is really nice and firm. I imagine when heated the hoses will show their flaw, so that's why I'm gonna get the SS lines. My brakes will see quite a bit of heat at the track.

Why not try the line first then? You are going to get it anyways. You may not need the extra displacement a different MC gives you, but the SS lines have its benefits weather you upgrade the MC or stay with stock. I am really liking my SS lines now. I may not even need the new pads.I really want to brake test this thing at highway speeds lol. I think I will go for a ride now.

I opted for the m/c swap because I was gonna replace the cheesy levers anyways and the m/c kit with levers was only a few bucks more. Like I said earlier, I REALLY liked the way my bud's lever felt. I put a Honda RC-51 m/c and SS lines on my ninja 2-fitty track bike and it has the best lever feel of any bike I've owned or ridden.

How is the eBay master cylinder kit working for you? I'm very reluctant to get an eBay M/C, but I feel as though we have an incredible lack of M/C options. It's pretty much stock or Been no. Anyone have easy success bolting a front master from a different bike on their R3?

I stuck a Ninja 650 master on mine when I did the R6 caliper mod. It's a bigger master. I think it equates to a 16mm. I would have kept that cause I am cheap but it wouldn't allow for clearance with my vortex clip ons so I went with the brembo 15RCS. I think something from an actual SS would be too big, as Those are pushing fluid for dual 4-pot set ups. Maybe something from a single caliper set up, like a duke 690 if you don't want to spend money on a brembo kit.
