Just swapped my 2014 v4r abs for a new 1100 and love it, I have only covered 300 miles so far so can't open it up yet but just love it. The seat is night and day different, feels really comfortable for me at 5.10 and even revving to 6k seems quicker with more torque and pulling power. So I would say spend the money if you can afford it. But is it the 3k to 4K more worth it. Yes of course if you have. If not stop with the V4r or spend a bit and upgrade to a 14 aprc abs.
I've recently had my suspension tuned and a few small adjustments to the bars etc, damn this bike is good now!1100 factory is awesome, best bike I have ever owned and I have had loads. For the price difference over the RR, get the factory. Better paint scheme, Ohlins are just brilliant.
