I saw this before they even had a U.S. distributor but I see they have one now. For the LT I would guess you would end up using a traditional hitch like their "Goldwing" model. You can see pictures of this here:
It looks like the center of gravity would be quite high when compared to a Uni-go or any of the other one wheeled trailers I have seen. That would probably accentuate the LT's low speed handling problems. While they look quite space age (Star Ship Troopers comes to mind, the bugs not the troopers
) and might match the lines of the LT fairly well I would not say I have warmed up to the styling. However, I don't think anything but rubber would ever touch the ground unless the bike tipped over.
It is more expensive than a Uni-go, approximately $2800 for the 200 liter model in England, and that doesn't include color matching or shipping. The adapters are about the same or even higher priced than a traditional hitch. Their 110 liter model is probably priced in the Uni-go price range but the Uni-go has a 140 liter capacity and a lower center of gravity.
The only reason I would go this route is if I needed or wanted the extra 60 liters of storage space that something like the Uni-go couldn't provide. Of course beauty is in the eye of the beholder and if I looked at it long enough the styling might grow on me. The first time I saw an LT, coming from the HD cruiser world, it's styling didn't really sing to me but it didn't take long for my perceptions to change
After looking into trailers I had decided on a Uni-go and then of course they stopped production. They should start delivering in January through the new U.S. manufacturer. I did get information from Dauntless Motors here in Washington State that they were designing a "Uni-go" type single wheel trailer and would be delivering by 1st quarter next year. I had already decided to go with a Dauntless Hitch so I may hold off ordering a Uni-go long enough to see what their design looks like.
At least we have choices
