Front Disc/Rotor.Tri/norton

Hi Guys,Are the Triumph(T140,Trident) & Norton discs the same beast?.......................Cheers Andy

No, they are two* completely different discs.
The most obvious difference is that the Norton discs are 10.7 inches diameter, and the Triumph discs are either 254mm (10 inches) or 250mm.

*(There are certain variations of 'Triumph' disc used on the various Triumph models, however none are the same as the Norton disc.)

Thanks L.A.B, that's useful info!!.................................Andy.
