A fellow Harley rider is a Guzzi nut, and rides his more than his Harley.
A friend of mine had one when I was in college (mid-60’s), and I remember what a monster it was. Made another friends BMW 50 look small.... I rode the Bimmer, but not the Guzzi........
I have ridden Norton, Harley, Honda, BSA, Trump, BMW(airhead) and nothing, but nothing is a stable on the road as an old Guzzi Loopframe.
Your friend will probably tell you that on the Guzzi, he feels totally secure and in control. Currently I have an old (84) GoldWing with top-of-the-line Pirellis on it. Still not the same.
