Can post 2007 SMC's be used on pre-2008 ST's?

Has anyone successfully installed and used an SMC that comes on the 2008 or younger ST, on a pre-2008 model ST?

In looking at Service Honda's parts fiche, the part #'s are different for the 2008 and younger. It makes sense because the post 2007 SMC is the one with the slot for a water drain rather than the small hole on the pre-2008 models:

thru 2007: 06454-MCS-G01 (superseded by the G03)

2008 & younger: 06454-MCS-R02

In looking at the Honda part numbering scheme, the difference between the two part #'s has to do with modification, but it says nothing about whether it can be retrofitted on the pre-2008 models. The fact that the R02 SMC has not superseded the G03's on the fiches would seem to indicate that R02 is not backwards compatible.

Anyone know for sure?

The 2008 and newer ST1300s use different sized front pads so the entire caliper is different. Not sure if that matters.

Search some of my smc threads...iirc I posted some photos of the difference in the piston and spring assembly.
I found the newer design with the spring not attached to the piston to work better in my 07. Any experimenting with parts is done at your own risk....disclaimer...if you pm me an email address I can email you pictures tonight when I get home.

Larry, I remember that thread. What I'm fishing for here is to find out if anyone has definitively determined if the slotted SMC can or cannot be used on a pre-2008.

Anyone?

I can measure my bracket that contains the smc on my 07 and maybe someone can measure a newer one to compare?
The calipers are cast one the newer ones...and yes they are longer..but they may not have change the size or shape of the bracket.
I will see if anyone local wants to stop by on a new bike to compare them for you.
