Diving into the brake pad thing a bit deeper, I've found out that the Brembo caliper is an off the shelf item, and is used on a few other motorcycles. BMW, Ducati, others. There are a bunch of options for pads and materials. Yes I know, BajaRon, EBC, Fully Sintered.... For those of you that can, those are great.
Others looking to get a wider option of organic, semi-met, full on race pads, look for pads for a 16 BMW R1200R. The BMW pads are Brembo's.
DBX, Niche, AHL, a bunch of manufacturers offering pads. I see organics as low as 10 a side, full on Brembo race pads about 120 a side.
Maybe you want to ride, aren't in a position to shell out a Benjamin. There are options.
Organics life is shortest, but kind to rotors. Semi-Met is organic with metals added for longer life, a little more bite. Full Sintered will last longest,at the expense of the rotor, but will stop better, with less fade when hot.
You choose. Again, I'm not saying you should cheap out on everything or anything. You need to decide what fits you, your wallet, and your riding.
