Front Brake Disc Offset/Bolt Pattern

[Nasher]

As I understand it, in the simplest of terms and ignoring some other detail:

Up to around the mid 2000s most Ducatis had front brake discs of 320mm OD, offset @9mm(depending on how you measure it) and 6 bolt mounting.
ie my 2003 1000SS and 2004 M1000.

After the mid 2000s most had 320mm OD, offset @15mm(depending on how you measure it) and 5 bolt mounting.
ie my 2005 999.

Now the point of my ramble above.
Was there a bike fitted with a mid way disc?
320mm OD
15mm Offset
But with a 6 Bolt mounting.

Thanks

I think the 748R and 998R models had them, Probably exclusive to those models.

[Nasher]

Thanks Darren.

The Ducati part number appears to be 49240371a so I searched and turned up these and a few others.

Thanks Darren

From that starting point, and having found the Brembo part number, I've discovered that they are pretty much standard fitment on later larger Aprilia bikes, so I should be able to find a really cheap knackered pair to mock up what's in my head before committing any real money.

[Darren69]

Glad my useless knowledge came in useful to someone. I did try to look for the Brembo part number for that reason but failed, Standard Aprillia stuff will be a load easier to get and cheaper than 998R parts for sure.

I actually thought they changed the disks to allow radial calipers but they don't appear to be, it was a SBK Homologation change, maybe for the forks? I dunno but I think someone on here has a 748R that can probably check measurements for you?

Öhlins forks to complement the rear shock perhaps, Simon?

Nope.

Not letting on until I know it works, and that will be a while as the 999 isn't finished yet because I've been out of action for a few weeks.

[Luddite]

Intriguing!

Fancy wheels maybe??

By the way, what's the Brembo part no. for this? I was looking through my old Brembo catalogue and I couldn't find anything suitable.

[Darren69]

Yea, I did look for the Brembo part number for you when I found the Ducati one as I thought it would help with finding other makes etc but couldn't find one.

I used this to fond the 748R part number:

Mmm, maybe looking again that part number isn't that specific, and appears to relate to earlier bikes on other sites.

More research needed I think.

Yes, that particular disc (78B40870) has a 10mm offset and was what I considered fitting to my S2R before I decided on Galfers.

This from the Carpimoto site (questions and answers) https://www.carpimoto.com/en-GB/4129...r-78B40870.htm

"Question: Hello, I am wanting a 320mm brembo 6 hole disk with 64mm inner diameter as pictured in you your website with part number 78B40870. Can you tell me if this disk has 0mm offset ? This is what I need for my custom bike. Thank you.

Answer: 78B40870 offset = 10mm"

I think the 15mm offset discs are quite rare animals.

I hope it's nothing serious old bean? I also hope you're back in action now?

Thanks Mr G.

I managed to pop a Bursa at the gym a few weeks ago, then spent that same afternoon carrying Concrete Fence posts about on my own and digging holes to repair storm damage.
Because I was compensating for the Bursa pain I tore a hamstring, which is still really uncomfortable.

Then Lady Nasher brought 'the Lurgy' home from school and I've been testing +ve for 11 days.
Despite having all my jabs etc it's really taken it out of me.
I manage to work from home until mid afternoon then collapse.

Oh, and have had to cancel my first two Physio sessions for the Hamstring because they don't want me there - obviously.

Dreaming up projects is keeping me going.
