The NX250 cylinder (and the XL350/600/NX650 and some XR600/650 models) got 11mm diameter (see below). The Xr250 master cylinder has 1/2 inch (12,7mm). At least the one I got. So if you take a xr master cylinder, pulling the brake lever will be harder in order to get the same brake power, but it will not improve it. Something that may work is an oversize kit from EBC. Since NX250 And XR600 share the same brake calipers, you can take a XR600 280mm brake disc http://www.jcmotors.com/p-29365-ebc-...x#.T96uooE-2Vk
Thats an example for an 1/2 inch master cylinder (Xl250 degree)
