When KTM revealed its 1290 Super Duke R at EICMA, it made it very clear the show bike was a prototype. An actual production version is on its way, as recent spy photos indicate, but the actual prototype displayed at Milan still maintains an aura of mystique. The specs sheet, for example, was intentionally vague. […]
Wesll Quad Prototype
Four-wheeled streetbike doubles the fun
A number of manufacturers have tinkered with various three-wheeled motorcycle applications over the years. Companies like Piaggio, Can-Am, Brudeli and even Harley-Davidson have produced unique trikes with ranging levels of success. The Wesll Corporation is attempting to do one better, literally, as it develops a four-wheeled mechanism that could be applied to many different kinds of bikes.
The working prototype involves a tilting mechanism that allows lean angles exceeding 50 degrees. Tipping the scales at a sprightly 310lbs, the 500cc quad has 28-inches of wheel travel! While the prototype looks like a lightweight ATV with wheels for the street, Wesll’s website offers animated renditions of the four-wheeled, leaning mechanism on a Kawasaki, Aprilia and even a Ducati. The site backs up the technology by saying that, “Engineers have long known that leaning a four-wheeled vehicle, to mirror the capabilities of a motorcycle, would provide greater speed and efficiency.”
Getting the system approved for the street will indeed prove to be a challenge, likely even more so than the aforementioned three-wheelers. Apparently, owner Tom Wesll isn’t interested in making the system available as a kit, but would prefer to work directly with OEMs in hopes that they will adopt this system. I would assume that this endeavor would prove to be an even bigger hurdle, regardless of how fun the system looks!
