oh, Graham, hello mate
The KTM is relatively sterile. I bought the SM for commuting and it's great for that, but it's not in the same book let alone on the same page as the S4Rs. IMHO (and other SD/SM owners), the Superduke is like a sporty supermoto, whereas the S4Rs is like a relaxed sportbike.
I got the duke from, er, let me go and check... Hyside in Essex (inside the M25 so still safe). They have Ducatis too so you could ride both back to back and let us know what you think.
