I spoke to Traxxion (Dan) yesterday on these topics:
1. The Anti-Dive. This is completely Disabled with the Traxxion modification.
2. Selling parts vice going to one of their facilities or contractors for install. The left fork "often" requires some lathing for the Traxxion cartridge and Traxxion wants to ensure this is performed properly to their specs. They will sell their products, but they HIGHLY recommend one of their dealers do the work. If you remove your forks and ship them, that'll work for Traxxion too.
3. Triple Tree Rake & Trail. Are the same as stock. They make a triple tree for triking that extends the rake a bit, but their two wheeled mod has the same rake & trail as factory.

Hope this helps anyone contemplating a decision.

Cheers,
Steve
