A new four-cylinder, 1,650cc motorbike, the Bienville Legacy, will be revealed for the first time at this year’s Goodwood Festival of Speed.

The Goodwood Festival of Speed will host the global public debut of the astonishing Bienville Legacy – set to be one of the most powerful four-cylinder production motorcycles ever created – on 25-28 June this Summer.

Staged every summer since 1993, the Goodwood Festival of Speed is the world’s largest motoring garden party, set against the spectacular backdrop of Goodwood House in West Sussex, UK. Over 600 cars and motorcycles spanning the phenomenal history of motoring and motor sport take part, with some of the most legendary figures from the sport as well as international celebrities regularly attending.

Highlights of the 2015 event, which takes place on June 25-28, include the Moving Motor Show presented by the AA in association with The Telegraph, Forest Rally Stage, Michelin Supercar Run, Goodwood Action Sports, Cartier ‘Style et Luxe’ concours d’elegance, Drivers’ Club presented by TAG Heuer, FOS Air and Bonhams auction.

Born from Bienville Studios in New Orleans, Louisiana, the JT Nesbitt-designed Legacy has been in development for over three years and is widely acknowledged as one of the finest examples of two-wheeled design ever produced.

Bienville Legacy is a weird, vastly overpowered and visually shocking motorbike with a completely unique suspension system. The Legacy advances motorcycle design with patented suspension leveraging one composite leaf-spring with the engine mounted at its centre. Carbon-composite blades allow for rake and trail adjustment for the first time on a production motorcycle.

Three concept models have been produced to-date, establishing an exquisite bill of materials in titanium, carbon fibre, leather, and mahogany. Powered by the American-made 1650cc Motus V4 engine, production models will be supercharged and provide up to 300bhp.

The Legacy will be ridden up the iconic 1.16-mile Goodwood Festival of Speed Hillclimb by Jim Jacoby and Scott Miller. Both founded the ADMCi Foundation which has supported the Legacy project from its inception.

The Legacy is just the latest addition to a two-wheeled entry that includes MotoGP legends Valentino Rossi, Casey Stoner, Giacomo Agostini, Freddie Spencer, John Surtees, Jim Redman and Kenny Roberts plus a celebration of Yamaha Motor Company’s 60th anniversary, featuring an astonishing array of bikes from the Japanese manufacturer.
