This is a write up on the 2d which is last years model.

The front section of the Tesi 2D is uniquely innovative: Instead of employing the classic fork, the Tesi 2D has a technologically advanced aluminum swing arm that separates the steering system from the damping system to offer perfect handling in all situations. Trail and steering angle remain constant on the Tesi 2D under all conditions, creating more neutral front wheel behavior when cornering, as well as a more constant braking sensation.

This steering concept is possible thanks to the Di Fazio System.
