Congratulations on the Dark Stealth. I love the look of them and I've only ever seem one on the road
Make sure you look after the paint properly because it's quite hard to look after.
Regarding your problem.
It's been known to happen a bit with brand new DUCATI's.
My Streetfighter did it randomly a number of times(4-5), with it happening twice on the first day on mine, and very early on during the running-in phase then it tapered off to become absolutely non-existent. Others on Streetfighter forums reported the exact same thing.
My 1199 did it as well quite a lot but software updates fixed it.
Others on this forum also had the problem early on in production.
Nobody really knows what causes it, but there's reasonable speculation in some quarters that it's related in some way to the TC???? It ties in pretty well with your experience of going over a bump
It's inconclusive though
I believe there "may" be some truth to it, but I personally think it may also be because one or more of the computers are in the earliest stage of a learning curve.
Also another contributing factor could be that under certain conditions, the engine is running very lean at low RPM's. Combine this with a tight engine that's still to loosen up and it's not inconceivable that it may stall/cut out randomly.
For your information.
The earliest versions of software installed into the 1199 contributed to random cutting out at low speed whilst down shifting and decelerating.
Like when approaching a set of traffic signals with a view to stoping or to make a turn.
As stated above, new software updates from very early on has since fixed the problem.
I would suggest you take note of it for future reference, with a view to reporting it to the dealer if the problem persists.
I know it's of no real help at this stage
Especially as it's so random and unexpected when it occurs
Get out there and have some more fun on that black beauty
Keep us in the loop as to how it's going.
Enjoy
