What the juddering f.... (899 panigale)
Discussion
Quite literally, what could possibly be going on here? 2015 899 is on 14,220 miles today and while rolling along in 2nd gear, when I came off the throttle I felt a few fairly violent judders. My legs felt like the engine was trying to jump forward. I tried to replicate it and it did it again. I went out for a ride just now to see if it was still there, and sure enough in 2nd and 3rd gear while doing reasonable speeds, when I came off the throttle it juddered quite violently multiple times.
I’ll stick it in for servicing tomorrow, but wondered if anyone else had experienced this.

At least one! Chain is knackered. Honestly glad to be laughing about it, could have been a complete disaster.
My guys always stress having the chain lubed and checked every 500 miles. Bike has been sitting in the garage and used infrequently for the last 3-400 miles so paid it no mind. Huge mistake! Lesson learned.

Did you have the chain done at 13k or was it just recommended and was never changed?
I think it’s got the wrong length chain, the picture doesn’t show the full extent of just how loose it is as the exhaust is actually holding it up.
It was definitely changed and lubed as I remember the colour was different to the stock chain. They’ll have everything on the service history so I’ll go over that on Monday.I think it’s got the wrong length chain, the picture doesn’t show the full extent of just how loose it is as the exhaust is actually holding it up.

He has already said the chain was new at around 13000 miles. To need a new chain at that mileage suggests that the original chain wasn't looked after either. Sprockets we don't know about, so they may have accelerated the demise of the second chain, but new 0/x-ring chains initially stretch a lot even if oiled. My GSXR didn't make the running in service before I had to tension the chain significantly, so over 1000 miles on a new chain without any maintenance and possibly slightly worn sprockets could be all we're seeing here.
I still struggle to see how anyone could walk up to the bike to ride it and not notice that though. Would he notice a flat tyre?
I would indeed notice flat tyres as tyres on all my cars are checked religiously before I move off, cheers.I still struggle to see how anyone could walk up to the bike to ride it and not notice that though. Would he notice a flat tyre?
The new chain was put on as the bike had new tyres going on and the shop mentioned the chain wasnt looking it’s best. Reading on a Ducati forum people have been getting anywhere from 8-20k between chain replacement, so 13k would seem ok. I have little bike mechanical knowledge so if something is recommended, I have it changed for peace of mind.
The chain issue I didn’t notice until the noise/juddering suddenly happened, which was very obvious, hence the OP, hence it being taken in immediately. In all honesty, it’s never been in my thoughts to check the chain as I didn’t know it had to be checked beyond the servicing schedule and shop recommended lube/check.
I’ll see what they come back with. Gif below to give an idea of just how slack it is. Link will prob expire within a day or so.
Chain slack
Cheers for the advice. 
Making a list of all this to take down to the shop tomorrow. In my mind, the bike gets light use as it doesn’t go on track and is used primarily for zipping about town to avoid traffic. With this in mind I wouldn’t have expected something like this to occur.
The more replies I read, the more fortunate I feel sitting here as it could have been a lot worse in terms of personal safety!

For the time being you should just tension it and oil it. Contrary to what some have said regarding too many links etc, I expect if you move the wheel back 5-6mm (around 5 turns on the 8mm adjusters) you'll probably take all that up.
Then replace chain and sprockets at next service unless they give cause for concern ( noisy if you spin the wheel).
I'd be more annoyed by the totally avoidable exhaust/ swingarm damage if it exists
