That sounds right. My interest has only been in the SR which picked up the skinny 17s, VSC etc., ADD, and presumably the bigger brakes,as standard in late 2013. I'd be surprised if any SR model without the electronics package picked up bigger brakes, which would mean only the wide wheel VSC (option pack) ones prior to 2013.
It has appeared to me that a few of these changes seemed to hold hands on the assembly line. IE Get one, get all.
Again, not sure, but I would expect that any M/C changes would have accompanied that package, regardless of which model had the package.
For anyone contemplating the upgrade it would certainly be handy to know for sure which models to chase down for an upgraded M/C, if it became necessary. Genuine spares may be gold plated, or they may not.
