these are available new from various Triumph spare parts suppliers.
If you don't want to order from England and there is nobody in Switzerland supplying these (can't believe that) try Joe Seifert (Norton Deutscheland) in Germany. His email is norton@nortonmotors.com or phone him on 0049-8105-271881. He will be able to help you.

If I remember correctly, the Harris disc is not exactly the same as a Meriden T140 disc.

The Harris disc is part 38-0009 and I think they may be difficult to obtain.

true, the Triumph part number for the disc up to 1983 is different to that of the Harris part because the supplier changed.
But the two discs shouldn't be too different as both are 254mm diameter and have 4-bolt mounting.
If they are different at all it is in the offset and that should be easy enough to correct by modifying the hub accordingly.

Thank you for the information,
the Harris discs has 260 mm diameter and have 4 bolt mounting.
The brake calipers ist made by Brembo,maybe the discs too.
I want to order from England , but i don’t find any internet offer with the Part Nr.38-0009.

Cheers,Roli

Hi
I was searching for a Harris Brake disc a year or so ago.
I could not find the disc PN 38-0009 anywhere. I tried many countries.....
The problem is that the Harris disc is narrower than the PRE-Harris brake discs. The offset is about 5mm less.
I could not find an equivalent disc on any other bike or did I want to machine the hub.
Eventually I found one (disk) in Austrailia of all places and have since found a couple of second hand ones.  If you find someone who has these still grab one for sure.

If you have any other useful HARRIS info I have started a Harris webpage specifically for this model.
www.triumphbonneville.co.nz
Because its hard to find info on these bikes sometimes.

Cheers
