I personally haven't ridden an Evo so do not know if it is a trait as such but I assume this isn't something that you have just recently started to feel?

Either way do the easy things first.

Check the tyres are in good condition with no noticeable squaring off of the rear and are at the recommended pressures.

Some bikes are more sensitive to these things than others and a front running a low pressure can make it feel rather slow steering which might manifest itself as understeer when riding at reasonable speed.

Of course as already mentioned check the suspension is at factory settings as per the manual (at least until you know what a base feeling is like) which may or may not be how the bike arrived from the previous owner or even the dealer (it certainly wasn't unknown for Ducatis to be all over the place a few years ago although I suspect quality control has improved somewhat).

Then go a little whizz around ideally on a route you can easily repeat as you make any changes to see if it feels any different.
