Never tested the stock brakes,they might be good,don't know but there's one thing,i hate these casted cheepest for sale surfaces.
Of real concern: a radial Brake Pump:i highly can recommend.
The PVM-type here:3 different angle-fixings,so you can measure out the Brake pump up to your individal
sentiment.Do what you want: change the
lines,use some race brake pads,take titan screws for the
caliper-halfs...,even all together,you've got not 40% of the effex changing the brake Pump.
Here: a PVM milled one 17mm Pot for 4 piston calipers ,19 mm pot for 6 piston....,
high Quality Product from Germany:advantage vs. Brembo:milled , available, and you get spare Parts
Always some Radials on Stock : fast delivery -mailto: email@example.com
The Calipers:a real advantage of the RC51-Fork,you can change your calipers and Brake discs diameter every day ,if you want.
If i had the Time i would use 300 mm diameter Brake discs,a (or two) monoblock Calipers and manufacture a fine milled holder.
Do you like Gold:?i don't like ,so disassembled this PVM-Monoblock.Black anodized is ok,a RC51 shouldnt look like a beauty,more like a weapon - dull,like this:
To give some prices: the Brake pump is about 380 $
the Monoblock calipers:each 875 $ incl. titan Pistons
