Anyone know what the Borrani front 19 and rear 18 inch numbers and width should be on a 74 ?

Graeme

Hi Graeme

the front is the same as the blue/gold Mark3 a 19 inch WM2 with 4741 drilling code

the rear is the same as a RT 4626 WM3 and 36 spoke not to confuse with a 4626/1 with is a 40 spoke rim for the 750 Sport rear brakedrum

According to Massimo Clarke, Graeme, they were the same as fitted on the (drum-braked) Desmo and Mark 3.* In which case, I think the sizes are:
19 x 1.85(WM2) x 36
18 x 1.85(WM2) x 36.

Sorry, don't know the Borrani codes. You could try asking Howard at Disco Volante, seeing as he's a Borrani importer - Howard's on this Forum. But for what it's worth, the parts book I have for the 1974 Mark 3 says that the Ducati part numbers should be:
Front: 0682.77.104
Back: 0682.80.100

* Initially, I thought this couldn't be right for the front one, the Scrambler one being 19"; but I see that Mick Walker says that the 73-74 Mark 3 used a 19" wheel.

Thank you gentlemen that what I needed.

Hello Eldert,

Thank you for your earlier answer.
Now I have been wondering about the drilling code you mentioned. Does 4741 tell a rim maker what angle to drill a non drilled rim?
And how does the /1 change the drilling from a 4626 to a 4626/1 ?
Are you able to tell me this?
I'm interested to know, not that I will need to do any drilling, just interested.

Regards
Graeme
