Looking for a uk source for a floating rear disc rotor for a 86 FLHT

does anybody know of a reputable source for these?

 

No! Your rotor is a ruddy great cast iron thing which is unique to the touring range and an odd diameter. It is also a lot thicker than conventional bike brake discs. When I replaced my front brakes I couldn't find anything suitable for the rear. I now have a 2007 swinging arm and wheel, with a modern Harley floating rotor.

 

thanks not the info I was hoping for

yes rotor is too thick for harrison 4 piston caliper

however I have a contact who runs a tool room who thinks it should be possible to machine about a mm or so off it so it will fit the caliper

option 2 is a shovel 16 spoke rear wheel, it takes the normal rear disk and still uses a 3/4" axle
