Also Fly by wire throttle assembly. Possibly slipper clutch. I'm hoping they would've replaced the horrible radiator fan also.
I'd definitely wait for the 16' unless you can find a 15' at ridiculously cheaper price.
The KTM official website has just been updated to show 2016 models. The Duke is listed as fitted with a "PASC anti-hopping clutch"; The RC, however, still shows the usual "wet multi disc, mechanically-operated clutch", as well as the standard 300mm front brake rotor. No mention of ride-by-wire for either model.
