As part of my overall S2R800 upgrade, I purchased some 4 piston, front brake callipers from an S2R1000.

Side by side, they make my current callipers look puny. And no, I'm not holding the new ones closer to the camera.



No wonder is such a popular upgrade.

Can't wait to finish this mod so I can feel the power.

Might have to start lifting weights to build up my arms so I can hang on. 

brakes just slow you down anyway....

how much more does the new setup weigh though?

Brakes are for sissies.   

How much did that run you? Are you upgrading the BMC to a bigger size? I def wanna do this next.

Oooh, that looks nice.

Reckon they'd look even nicer in gold...

Hey, I think those were mine!

If I remember correctly, the 4 pistons are still lighter as the 2 pistons have that silver bracket that the caliper mounts to.

Um, about $150 USD plus postage. (Yes Darkstar, I believe they were yours).

I assume BMC means Brake Master Cylinder. I don't plan to at this stage. I just need to buy some rotors and I have dual braided lines I think might fit.

As for the extra weight, I don't think I will be worrying about unsprung weight when some numpty driver pulls out in front of me.

My memory is a bit IZ_, but when I switched over from the stock setup on the M695 to 4-pad brembos with narrow-band rotors I seem to recall that the total package was a good bit lighter.  I weighed things, but I can't find the numbers!

Are you saying my brakes are... small?

Looks like your caliper just climbed out of some VERY cold water.

Brake envy is a very common thing and very normal.

Actually they are easier to find in gold but I wanted the black ones as there is no gold on my bike at the moment and I think it would look out of place.

Nice thinkin' Techno. That's why I went for the silver 4-pads like BK's.

I have since found a bit of gold creeping onto the bike

EDIT: Oh and when I saw the two calipers side by side I thought 'don't those 2 piston calipers look cute' - still do when I see them on a bike.

Embrace your inner Matty!

There's a big advantage to the black ones, and that's cost.  Having bought gold ones, I fear the days are numbered for my black rear caliper.
