| 16x20 was the reply from Fylde,so no good to me.Isnt 16x20 the norm for single disc,its listed as fitting Super Sport 750/900,werent they twin disc.
Now you blokes have them fitted so you know what works....but."The racing Brembo radial is 19mm,with the decrease in braking force balanced through softer pads with a higher coefficent of friction.For street use,such pads may not be suitable."
Standard 88-90 851-15mm,most 748/9..-15,16mm,748R-15mm,999-18mm.So if you were guided by above 19mm should result in scary brakes/strong fingers. |
