I thought this would be a straightforward question to answer but I'm now confused. I haven't had experience of this myself so I checked part numbers. If you go to this page for the 2011-2014 SV:
https://www.fowlersparts.co.uk/brows...ur/all-colours
and scroll down to transmission which is where the chain and front sprocket are to be found, you'll see 4 options. The top 2 options show a 108 link chain (maybe the N model), the next option 650SAL1-E24 shows a 114 link chain so that's the S model (with ABS?), right? But, the next one down is the 650SUL1-E24 and it's back to a 108 link and yet it appears to be an S.
I can see why there's confusion in the marketplace.
