=Wisconsin-based Scorpion Trikes, with their DIY kit that features two wheels at the front. it requires no frame modifications and very few extra parts other than those in the kit, which means the conversion gets you two wheel independent suspension and an integrated look, all in an afternoon’s work.
Scorpion Trikes say that each kit is built for a specific model, with the first one custom-tailored for the V-Rod, with future versions planned for Harley-Davidson touring bikes with an FL frame. The manufacturer expects that their kits will hit the market somewhere in the USD 5,000 range (not including shipping and installation), with the added proviso that a few parts not supplied with the kit will need to be purchased separately from a local Harley-Davidson dealership to complete the installation.
