The Bienville Legacy Is An Engineer's Acid Trip On Two Wheels

JT Nesbitt doesn't design bikes – he completely reimagines them. You probably know him as the man behind the Confederate Wraith and G2 Hellcat, and after eight years of engineering he's created this, the Bienville Legacy, a 300 HP superbike that uses a single carbon fiber leaf spring as the suspension.
The Legacy is the first commission by the American Design and Master-Craft Initiative (ADMCI) and created by Nesbitt's New Orleans-based Bienville Studios. The design has been on the table for nearly a decade, but work has been underway for the past two years, culminating in what Nesbitt describes as "an entirely new vehicle, reinventing how motorcycles function from the ground up."
The engine is a fuel-injected Motus MV4R, which in naturally-aspirated form puts out 185 HP. But it's also offered with an optional supercharger, bring output up to over 300 HP in race configuration. That four-pot acts as a stressed member, nestled inside a 4130 chromoly chassis that only weighs 23 pounds. Overall weight is around 400 pounds, thanks to carbon fiber wheels at each end and a split system, four-gallon fuel tank.
But the real – and very patented – party piece is the suspension, which uses a single carbon composite blade that spans from front to rear. That makes the entire bike lighter, and coupled with the front girder forks, suspension adjustments are infinite. It's also meant for outright speed, with a long, 62.5-inch wheelbase, and matching 250mm rotors with four-piston calipers at each end.
The Legacy is as much a rolling work of art as an engineer's hallucinogen-fueled wet dream, and while there's no mention of price, the fact that each bike – down to the hand-crafted saddle – is built around the rider should dash any hopes of seeing it at your local meet-up.

There is, however, an element of the old world in his design process that bears noting. Nesbitt believes that the aesthetic appeal of vintage machines is a product of their conception – in the mind of a person. A person can conceive of an object in their mind, designing it in three dimensions within their mind’s eye. If each component on the machine is designed this way it lends a human element to the device, as no part is beyond the comprehension of a human mind. Introduce computer modelling and suddenly you have elements that are so complex that they alienate the viewer. To respect this human factor, Nesbitt designed each and every component of the Legacy with pencil on paper. He sketched every nut, bolt, fixture, linkage and accessory. A computer was only introduced after the component was designed, when the sketches were adapted into Solidworks files by volunteers David Czarnecki, Austin Porter and David McMahon. The files were then sent to Scott Tudury at Apex CNC in Morgan City, Louisiana. Scott worked as the design engineer and lead machinist, translating the sketches and files into metal and performing final milling of the components.

Not exactly my style but damn (!) these bikes are beautiful. The workmanship is supreme and design very innovative. A very well balanced design, futuristic but it appears to breathe quality.
