As a former owner of mulitple Ducatis, as well as Laverda and Benelli, and former "Italo-phile", I'd say that it is not a "replacement' as much as it is an "alternative".
They are much different rides.
The main one being that the focus with the Enfield is on the ride along the way, and not so much in the "getting there", if that makes any sense.
With an Enfield, you don't "fly past" everything at high speed, so you get to notice and process what's around you during the ride. You get a different perspective.
It's not "hurried" and you have a very different experience from a ride like this.
IMO, in the modern world of motorcycling, there's too much emphasis on "rapid transit", and not enough emphasis on enjoying the ride. We don't get our biking kicks like an amusement park roller-coaster thrill ride. That's fine for what it is, but we have something different.
Plus, there's nothing like the "thump" and feel of a single.
I spent almost all my motorcycling life on bigger Italian twins and multi-cylinder bikes. It took me a long time before I ever even tried a single, and it was a Bullet.
I never knew what I had been missing.
Now I don't even want any more twins or multis. I'm addicted to singles.
And I can tell you that I notice a very distinct similarity of riding feel between my Bullet and my old 750 Ducati Sport bevel-twin. They both pull hard with good torque and feel solid and controlled. It's that good. It's just that the Bullet has a bit less overall power and speed, but the "feel" is similar.
I think you'll like it.
