Can't really comment on the MV as have never ridden one, however the new Tuono will be epic!! I swapped from a Tuono V4 APRC to my S1000rr and part of me really misses it's character.
The electronics are just superb. Launch control - funny but pointless!
Wheelie control - actually works.
Traction control - absolutely amazing. Seeing the little orange light flickering when you're on the power is very reassuring! Plus, being able to flick up and down whilst on the move is brilliant.
And now for the noise, it's like thunder!!
It's comfy on the road and plenty fast enough for trackdays. I've had a few people come up to me after a session genuinely surprised at it's pace when I overtook them!
I had a few recall issues with mine and yes parts can be a pain to get sometimes. However if you find a decent mechanic close to you (I can recommend you one in the South) then it's not too bad.
...........I miss that V4!! Might have a quick look on Autotrader.......
