Dont worry
NBS996 is right. There is specific motor industry legislation to cover customers in instances like this for 3 months I think.
The best thing to do is to write to Ducati UK and send a copy also to Ducati Aylesbury, send them Recordrd delivery. Dont forget to keep a copy for yourself
Ducati UK and pretty good at sorting out disputes between Dealer and Customer.
Make sure Ducati Aylesbury dont try to use up your warranry on this.
I once bought a brand new 748 from Ducati Aylesbury and on my wat home from picking it up the throttle stuck open
