...this is what they said about their Billet Triple Tree;

Huge advantage with the triple tree. The fork brace is trying to address the triple tree actually flexing, the fork tubes themselves do very little flexing at all as they are 45mm. The OEM triple is pretty cheaply made, and is hollow and has no cross bracing underneath. We have one mounted in a steel plate with a fork tube sticking out of it as lever, and you can really make it flex by hand. Ours made of billet doesn’t flex at all. You will notice a big difference with turn in, and it even feels more solid on the highway.
