Brake disks on a 650 TA

[Titch]

I need a bit of help please...

Can anyone who has a 650 Alp please tell me if the brake disks mount to the wheels by 4 or 6 bolts...?

And if 4 bolts... what is the distance between the bolts diagonally...?

Thanks for any help/info..

Don’t want to be a nerd

but these are usually quoted as PCD Pitch Circle Diameter i.e

The PCD is the Diameter of the circle centred on the Axel and running through the bolt centre centres.

so hopfully the answer is PDC 117.5 4 hole and you have not got T & D mixed.. could be expensive when ordering the wrong stuff

I need both front and rear for a four bolt mounting, as the Dommie wheels I have are four bolt mounting for the disks.

Looking at the pics in the haynes manual for the 650 Alp it looks like they have a four bolt mounting also, and wanted to know if the disks from a 650 Alp will fit onto a Dommie wheel...

The other point to add is that Haynes states that the 650 has the same size disks as the 600 Alp, that being 240mm rear & 276mm front... is this also correct.. As like Raymo said, it would be a bit expensive to order the wrong disks...

Thanks for any help

hi titch will check out my 600 tonight and let you know

[Titch]

Right then.. just had a phone call from a mate of mine who owns a bike shop, and he gave me the phone no. for EBC brakes tech team... after phoning them have just been told the following info:

Standard disks for a Dommie are 220mm rear & 256mm front

if I want disks of 240mm rear and 276mm front to fit the dommie wheels I need disks from the following bikes:

Front = XRV750 90-03 models
Rear = CB500 97-03...CB750 92-02...CB900F 02-07...XL600 91-99...XL650 00-07...XR650 88-89

So this should help me in the look for the right disks.

He asked for the diagonal dist, not the PCD

Btw for what its worth David Silver have the oe 650 discs for about £51 ea (I just ordered a pair), thats alot cheaper than direct from Honda! How does that work?!!

Anyway I thought they would be about £100 ea so I'm chuffed.
