New Buell 1125R redefines the sportbike riding experience
July 8, 2007
The Buell Motorcycle Company is set to break the convention of the superbike category with the Buell 1125R, an all-new, liter-class motorcycle that delivers an artful balance of street and track performance. Rooted in the core design principles and character that have defined Buell motorcycles for 25 years, the 1125R offers power, handling and agility that will take its owner to a new level of riding experience. The Buell 1125R joins the XB and Blast as a third and distinct Buell motorcycle platform. The Buell 1125R is expected to arrive in Buell dealerships in late 2007.
"We designed the 1125R from the rider down," said Erik Buell, chairman and chief technical officer at Buell Motorcycle Company. "The 1125R takes Buell to a new level of performance, while continuing to embrace the fundamental Buell principals of motorcycle design and offering a great motorcycle riding experience."
The Buell 1125R riding experience derives not just from its power, but from a carefully considered combination of engine performance, precise-and-agile handling, advanced aerodynamics, and superior rider environment and control, all packaged with distinctive styling that leaves many of the motorcycle's mechanical components exposed.
New V-Twin Muscle - The Buell 1125R Helicon engine is a new 1125cc DOHC V-Twin, the first liquid-cooled engine to power a street-legal Buell motorcycle. This compact, 72-degree engine is the result of a collaboration between Buell and BRP-Rotax, a leader in the development and manufacture of advanced engines for recreational products. The Helicon engine was designed to Buell specifications and is exclusive to Buell. It will be manufactured in Austria by BRP-Rotax. The most-powerful street-legal engine ever offered by Buell, the Helicon engine is rated at 146 crankshaft horsepower, and is designed to deliver optimized usable power, with a broad powerband across its 10500 rpm range. Its V-Twin design retains the styling and character that has always defined the Buell riding experience.
The engine is cradled in a new Buell Intuitive Response Chassis (IRC) with massive, rigid aluminum spars that double as the fuel reservoir. The new 1125R sticks to the three tenets of the Buell Trilogy of Technology - chassis rigidity, low unsprung weight and mass centralization - to deliver race-inspired agility and handling. The all-new front fairing and radiator cowling was developed using the latest computational fluid dynamics (CFD) models to provide superior aerodynamics, rider comfort, and efficient air flow to longitudinal radiators and a ram-air intake system.
The front wheel is supported by 47 mm inverted forks. A new Buell ZTL2 front brake features an eight-piston caliper based on the brake developed for the Buell XBRR racing motorcycle. A smooth-shifting six-speed transmission is mated to a new HVA (Hydraulic Vacuum Assist) Slipper Action clutch that uses engine vacuum to boost clutch-lever action and to provide a "slipper" effect when the engine is down-shifted at speed. A new underslung muffler has dual brushed stainless steel outlets.
The Buell 1125R offers an athletic riding position. Quiet Zone aerodynamics are achieved by managing air flow around the rider for enhanced performance and comfort. The toe levers on both the brake and shift foot controls are adjustable to match rider foot size. The instrument cluster features a large analog tachometer and a digital speedometer, plus an Onboard Diagnostic Information System (O.D.I.S.) screen and other interactive features. The fairing shape is inspired by the Buell XBRR and features six-bulb headlamps. LED turn signals are integrated into the mirror housings.
The Buell 1125R is available with Midnight Black bodywork, Diamond Blue wheels, Diamond Blue frame and swingarm, and Fusion Bronze engine trim.
