Tcs And Rider Modes.

I'm currently in the market for Speed Triple. I'd like, no need TCS but I'm confused. From what I can gather it was introduced in 2016 along with the Rider modes and Bar end mirrors. This year seems to be at my financial limit but many of the 2016 bikes on offer don't have Bar end mirrors and no clear statement of it having TCS and zero images of the left hand switch gear.

Would I be right in thinking that a lot of these bikes are actually the 2015 model registered in 2016? I've seen loads that are listed as 2016 but after seeing the switch gear or lack of Bar end mirrors they don't seem to have Rider modes which I guess they don't have the TCS either. Is the TCS limited to the R model or is it available on the S too?

Any help would be greatly appreciated.
