I've heard a couple of others infer this. Why more fun to ride?
It has a different airbox, so the aural soundtrack over 6K is wonderful.
It is very comfortable to ride - much more comfy than the R - your legs are much straighter.
The wide bars give you great leverage in the twisties, making the bike far more responsive and "chuckable" than the R.
The QS is much, much better than the one in the R, and it works down the box as well.
It (feels like) it pulls harder than the R, but that could be the upright position.
The upright position is far better for in town and commuting.
Downsides?
The seat height - I waxed lyrical (i.e. pissed and moaned

) about this in another thread, but I gave myself a metaphorical uppercut and told myself to HTFU

.
I can flat foot the bike at lights if I lean off to one side very slightly...and I'm used to this from my GS.
The vibes - 99% fixed now.
The looks....I am getting used to them now...all bikes (like women) have good and bad angles...
