    Brembo RCS19 on Gen2

    Hello,

    Has anyone installed a rcs19 master cylinder on gen2 before? If yes, how was your experience? I have a mc that is free from my track bike and am thinking of install it to my xr. I didn't really like the feel of the current axial master cylinder.

    any thoughts?

    ps: My bike is the European version with stock calipers. there are no recalls yet like the bikes in the US market.

    Thanks!

    have not installed, but I would check to make sure that the calipers are compatible with RCS19> I think that the piston size of the calipers on the XR are more suited to the RCS17. You could try, but may get a wooden feeling with the 'bigger' pump(RCS19) over powering the smaller calipers(32mm vs 34mm). I cannot confirm that my numbers are correct for the GEN2, but I have a Gen1 R and a Gen 1 XR and have measured those(R-34mm, XR-32mm)

    I’ve got a couple of bikes that I have changed the master cylinder with great results, but what’s the point with a bike that has ABS.

    The Same reason you do so on a non-abs bike. Get improved feel and feedback, and the possibility of increased stopping power with less input.

    brake power is really good with stock axial m/c but i can't say same thing with the feeling. So, my aim is increased feeling and more control on brakes.

    Take one off and measure the pistons.

    If you have a bike with ABS that is ruling criteria and nothing else, hence why go to a WSB or Moto GP race you’ll not find such.

    I have a set of full floating Beringer discs on a bike...so you need earplugs all the time just for the noise they make, but have 45000 miles on them and not a slightest hint of a wear lip on them because they never get hot and bothered, but changing the master cylinder just means you are going to bump into the ABS sooner.

    Winger you have a point. ABS is the weakest link for full performance . But on my gen 1 doing track it does have alot less brake fade and I do notice some improvement over stock. Biggest gains would be to bypass abs altogether. I wouldn't go back to stock.

    A larger diameter master cylinder will simply give you the ability to apply full force possible - with less fingers/force on the lever.

    Braking ability may still be restricted by pad/disc materials and ultimately by ABS cutting in.   

    I've not found the brakes on my '16 XR to be lacking, TBH
