OK. Yamaha developed the fazer to be a great bike which it is. They spend millions of pounds developing everything on every bike produced, to cater for what the bike would probably be bought for ie, commuting and general riding on the road in your case i guess, and they developed/opted for the brake pads/material that is currently used because they work very well on that bike.
Unless your going to ride it on track to well over what the pads were intended for, buy OE pads.
OE pads are actually very good, but iof you are looking for something with a bit of extra bite, then its a game of trial and error to find one that suits you.
I never had a problem with Bendix sintered pads in my road bikes, or goodridge pads, but EBC can be very hard and iv personally had glazing problems with the sintered ones, but thats my experiences where others may say they are great.
