Brough is Back with Brough Superior SS100

The new Brough Superior SS100
The new Brough Superior SS100 features an 88-degree V-Twin, a quadruple disc arrangement on the front brakes, and a girder front end based on the Fior concept derived from MotoGP engineering of the '80s and '90s.
Immortalized by Lawrence of Arabia, cherished by collectors, heralded for both its beauty and brawn, Brough Superior motorcycles are a breed apart. With a reputation as the “Rolls-Royce of motorcycles,” a Brough was notable for both its aesthetics and performance. Thanks to a collaboration between the company’s new owners and French firm Boxer Design, a new breed of Brough Superior SS100s are being marched out with hopes of returning the marque to prominence on the 90th anniversary of the SS100.

At the heart of the new Brough Superior SS100 is an 88-degree, 997cc V-Twin. The liquid-cooled engine has a power output said to range from 100 to 140 horsepower, depending on ECU settings. These settings will be established by the factory per the owner’s preference. The eight-valve, dual overhead cam engine features a 94mm bore operating at a 71.8mm stroke. The Brough’s engine serves as a main structural component of the chassis as it links the front and rear suspensions. The powerplant’s creation is the product of an alliance between engine specialists Akira and Boxer Design.

While its frame is made of steel, the titanium used in its trellis suspension triangles and seat structure aim to keep weight down. The aluminum-magnesium swingarm is connected to an Ohlins shock, the progressive link system fully

adjustable. The front end sees a double wishbone arrangement based on MotoGP engineering from the 1980s and ‘90s called the Fior concept whereby the double triangle fork disassociates braking and steering. The system uses an Ohlins mono-shock with preload capabilities to anchor the front.

One of the motorcycle’s most interesting traits is the quadruple disc arrangement of the front brakes. Four 230mm floating discs are stacked so they almost look like a drum. The discs are made of an aluminum-ceramic composite developed by Beringer in hopes of “reducing the gyroscopic effort and weight while increasing brake power.” Brough PR claims the quad-disc system increases power by 20% over a single 320mm cast iron disc, thereby reducing braking distance. The gyroscopic inertia of the four-disc arrangement is said to be three times less than that of a 320mm disc as well. The 4D Aerotec system is comprised of two radial-mounted, four-piston calipers teamed with special sintered pads.

With its 120mm wide front tire set out at a tight 24.6-degree rake angle, the new Brough Superior SS100 has the geometry to support its sporty disposition. The motorcycle rolls on 18-inch wheels front and back and only weighs a claimed 395 pounds dry. And while the new Brough benefits from performance upgrades, it’s easy to see the influence of its 1920’s predecessor in the shape of its tank and its girder fork.

Brash and beautiful, the new Brough Superior SS100 will be made in limited quantities just like its forebear. It reportedly will be ready for production in the second quarter of 2015 with an MSRP of 50,000 Euros ($67,587 US).
