CX/RS front disc??

[Moto63]

I’ve “heard” that the Honda CX front disc is a direct swap for a Honda Cb250rs. Does anyone out there know if this is correct?
I realise the CX disc is slightly larger in diameter but I intend to swap the front caliper too, so diameter isn’t an issue. It was more the stud pattern/centres
Thanks… Michael

In terms of bolt spacings, any honda with comstar wheels will have the same pattern, so superdreams, cx500 and even cb650/750/900. Whether the diameter and offset suit I can't say, but I know comstar wheels disks fit an rs hub cos I've done it albeit years. Ago.

I think I have a CB250RS disc lying about somewhere if it's any use to you? Yours for postage and a pint.

Many thanks for the offer Ian, however I also have an RS250 disc but I’m “upgrading” the front brake on the “different tracker” project bike. I’ve since found out that, yes the CX Eurosport front disc is a direct swap for the smaller original RS disc.
The CX disc being a larger diameter. So going for an EBC stainless replacement, along with a Royal Enfield scram master cylinder/lever and front caliper.
All that braking power….. I’ll be pulling stoppies at every set of traffic lights I come to 😁😉

Just to let you know. The Honda cx Eurosport front disc IS a direct bolt on swap for the original cb250rs disc.
I’m not sure it goes on with the original caliper in place with it being a slightly larger diameter. I’ve had a plate milled up to accommodate a twin piston Royal Enfield scram front caliper
