I tend to agree with TrikeTradersLLC. the Blue Trike, a trikeshop VW runabout, had a set of Springer forks. The angle of the forks was pretty extreme, and they were desogned for VW trikes. I had a brace made, and it seemed to make a little difference on older roads where the pavement was buckled or worn. On the GL1500, I put on a Superbrace, and to me there is a marked improvement in the ride through curves. Remember, the forks were designed to take the forces up and down through the steering head, and even when heeled over in a turn, most of the force is in the same plane. When we trike a motorcycle, the forces are lateral in a turn, causing more striction and side deflection, not the thing the forks were designed for.
