I like the front NISSIN pads as they come with the Bike stock, but they are a little more expensive and I replaced the front ones with ProX and so far so good, I like them ...
On the rear I changed the Nissins out at half it's life because they literally were eating away the rotor and I put some cheap Delta Braking pads on there, those are softer and usually do not tent to eat up rotors as much, but the break feeling is worse, not aggressive, on the Beta rear rotor I don't like them as much as I did on my other bikes, I only used Delta Braking pads in the last years with my previous bikes.
I am about to trow a new rear rotor on as the stock is getting very thin already, those Galfer that came stock are the rotors that lasted me the least time, on my previous bikes I used to wear several pads through one rotor, I don't remember exactly, but let's say 4 pads before the rotor was worn down, on the Beta it were only two pads and the rotor is shot... Probably the Galfers are a softer compound than the NG's I used be4...
Well I am planning to get this rotor as a replacement:
Yes, it's another Galfer (looks like I do not learn) , but I like that design more as I ride a lot in the mud.
Cheers !
