While not the same motorcycle, I found tire pressures to make rather significant difference to how my Norge handled. I am a life long sport bike guy. Nothing else in my garage is remotely close to my Norge. When I put the new tires on, I aired them up to typical sportbike tire pressures for the street. 34 front, 36 rear.

Then, while reading the owners manual I found the recommended pressure were a bit higher at close to what you describe. Once aired up to those pressures, the Norge was pretty agile at speed. Turns out those few extra PSI matter more than one might expect.
