If the front springs fitted now are still the oe one's they will not be to hard. The harshness comes from over damped compression damping (the 2014's feel is the same). All you can do is try lighter oil with a slightly larger air gap and the replacement springs. Well you can do the job right and send the forks away for a full revalve but that's expensive.
I'd try what hyperpro has said and if your still not happy try 5w oil next. I've had 10w, 5w and now 2.5w in myl Strom, each time it's a little bit smoother. It needs a revalve to remove completely but I'm to tight to spend that amount on a 4k bike.
If you firm up the front you will find the rear lacking, if your still on the oe shock that is. Good luck.
