Logo and Trademark..............................
The Buell Motorcycle Company is an American motorcycle manufacturer based in East Troy, Wisconsin and founded by ex-Harley-Davidson engineer Erik Buell. The company is the only significant manufacturer of sporting motorcycles in the United States. The first Buell motorcycle, the RW750, was built in 1983 purely for competing in the AMA Formula 1 motorcycle road racing championship. At that time, Erik Buell was a top contending privateer motorcycle racer. After completion of the first two RW750 racing machines, one of which was sold to another racing team, the Formula 1 series was cancelled. Buell then turned his focus towards racing-inspired, street-going machines utilizing engines manufactured by Harley. In 1994 Harley-Davidson Incorporated joined in partnership with Buell Motor Company as a 49% stakeholding minority partner and the company formed was renamed "Buell Motorcycle Company". In 1998 Harley purchased majority control of Buell, and it has been a subsidiary ever since. Since then, Buell has utilized modified Harley-Davidson Sportster engines to power their motorcycles.
Most Buell motorcycles use four-stroke air-cooled V-twin engines, originally built from XR1000 Sportster engines. After these were depleted, a basic 1200 Sportster engine was used. In 1995, the engines were upgraded with Buell engineered high performance parts, and further upgraded in 1998.
In 2003, Buell introduced an engine so efficient it passes emissions test requirements through 2008. It does this without the need for catalytic converters, or air injection, as is typical on other modern motorcycles. The new line of Buell XB models also incorporated the industry's first ever Zero Torsional Load (ZTL) perimeter floating front disc brake system, an "inside-out" wheel/brake design that puts the brake disc on the outer edge of the wheel, rather than at the hub. This design allows the elimination of some mass from the front wheel, reducing unsprung weight, and enhances the abilities of the front suspension. However, by placing the mass of the disc further out from the axle towards the perimeter of the tire, it does increase the moment of inertia. Further, the perimeter disc system increases torque on the wheel as a whole since the moment arm is increased. Other industry innovations introduced by Buell in the XB lineup were the "fuel in frame technology", and the dual use of the swingarm as an oil tank. Also, all Buell models feature a unique, dual-purpose, muffler mounted below the engine which helps keep mass centralized and maximizes torque through the use of a computer-controlled valve to switch between two exhaust paths as necessary.
Buell designs focus on providing good handling, comfortable riding, easy maintenance, and street-friendly real-world performance. Buell motorcycles are engineered with an emphasis on what they call the "Trilogy of Tech": mass centralization, low unsprung weight, and frame rigidity.
Buell engines are designed to be street-friendly both in fuel efficiency (up to 70 M.P.G. with the Blast), and in power (the 1203cc version produces over 100HP). They are also simple and easy to maintain. Buell two-cylinder engines utilize computer controlled ducted forced air cooling (no radiator or liquid coolant, just a variable speed fan that only activates as required), two valves per cylinder, a single throttle body, zero maintenance hydraulic valve actuation, and zero maintenance gear-driven cams. However, the motor retains a pushrod valvetrain, which was abandoned by Japanese sportsbike manufacturers in the 1970s.
