I ordered EBC organic pads in error for my Tiger 1050. They were no better or worse than the HH pads I normally use but wore out completely in 5000 miles. That's twice as quick as I would expect.
Not relevant to our old bikes I know, but it would indicate that they are made with a softer compound (recycled compost? How can brake pads be organic?)
before I fitted the twins discs to my 500,I briefly fitted the £25 EBC pads,in the dry ,they felt useless,no bite,hight lever pressure,
in fact ,I felt a complete lack of confidence in then,BUT !! in soaking wet,they worked great, ?? Go figure !!!
so I junked them btw,the pad material appeared softish and a slate grey colour,maybe the new 2014/2015 is better
