That tucked in look is common with springer suspensions.
it's amazing how different a degree or two is noticeable visually.
Neck angle, fork length and fork angle determine the trail of the front wheel.
notice if you will your mechanical forces (for steering) are behind the wheel axle. it behaves like a shopping cart wheel and wants to flip around backward, so either the neck angle or the rake has to decrease so that the wheel follows the direction of the movement.
These rake and trail numbers change as you brake or hit bumps and are worst in a springer so you have to give a bit more trail to a springer, as you brake the trail diminishes and the closer you get to that shopping cart issue.
