Just got off the phone with Dauntless (DMC) in WA. They have nothing for the guzzi. The triple tree product they used to carry is NLA from the mfgr and they have no new source. The leading link forks they have on the website was a 1-off custom for a customer and they did not develop any tooling as they went along. So while they could possibly do another 1-off ($3200-ish + 6-week lead time + my rig in their shop for the duration), they weren't real enthusiastic about it. Jay, the owner, said UNIT in the UK did the concept so well that most other customizers didn't try to compete -- they let UNIT have the technology and looked for other products to make their mark with.
Jay also told me that the leading link has been overtaken by the modified tree sets since for tube diameters have gotten larger. He suggests that I could do "95%" of what a leading link does at half the cost.
So DMC isn't a player. The search continues.
