I've got EBC FA18 graphite pads on my '81 .
I had two sets of OEM pads, dry stopping was good, but wet stopping performance, was about on par with Fred Flintstone dragging his feet on the ground, to get his car stopped .
I haven't seen any dramatic increase in brake performance in dry conditions with these pads, but wet stopping capability is greatly increased .
With the OEM pads, if there was good chance of a shower forecast, I wouldn't take the '81 out .
If you have ATE calipers, you need to trim down the metal back plate to fit, takes about 15 minutes or so for each pad .
If you have Brembo calipers no modification is needed .
I don't get the usual brake dust on the front wheel, I haven't washed the bike since January the front wheel is still clean .
Also not sure how long the pads will last, seemed to be a 'soft' brake compound .
