Buell XB models also incorporated the industry's first Zero Torsional Load (ZTL) perimeter floating front disc brake system, a patented "inside-out" wheel/brake design that puts the brake disc on the outer edge of the wheel, rather than at the hub. This lets the suspension function better, improving control and traction, through reducing unsprung weight on the front wheel, because only a single disc and caliper—with a corresponding reduction in bolts and brake fluid—is needed compared with the conventional dual-disc brake setup on most modern sport bikes. In an exchange in the pages of Motorcyclist magazine between Suzuki engineer James Parker, creator of the GSX-RADD hub-center steering system, and Buell's Director of Analysis, Test & Engineering Process, Abraham Askenazi, Parker conceded the ZTL system's advantage in unsprung weight. But he pointed out the remaining weight is located further out on the rim where it is most detrimental to acceleration and braking, and that there were potential heat transfer issues, and the need for one fork leg to be stronger than the other. Responding, Askenazi disputed all of Parker's criticisms, saying the ZTL system was 30% lighter than the brakes on the Suzuki GSX-R1000, and that the inertia of having the weight further out on the rim, and the heat generation near the tire, were not negative factors, based on testing. Askenazi concluded that testing and race track experience had proven the ZTL to be "state of the art."
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 muffler mounted below the engine which helps keep mass centralized with some models featuring a computer-controlled valve to switch between two exhaust paths as necessary to maximize torque.
Buell designs focus on providing good handling, comfortable riding, easy maintenance, and street-friendly real-world performance. Buell motorcycles were engineered with an emphasis on what they called the "Trilogy of Tech": mass centralization, low unsprung weight, and frame rigidity.
Buell engines were designed to be street-friendly both in fuel efficiency (up to 70 mpg or 3.4 L/100 km; 84 mpg with the Blast), and in torque (the 1,203 cc version produces 110 N·m or 81 lbf·ft). They are also simple and easy to maintain. Most Buell two-cylinder engines utilize computer controlled ducted forced air cooling (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.

Famous quotes containing the word technology:
“Our technology forces us to live mythically, but we continue to think fragmentarily, and on single, separate planes.”
—Marshall McLuhan (1911–1980)
“If we had a reliable way to label our toys good and bad, it would be easy to regulate technology wisely. But we can rarely see far enough ahead to know which road leads to damnation. Whoever concerns himself with big technology, either to push it forward or to stop it, is gambling in human lives.”
—Freeman Dyson (b. 1923)
“If the technology cannot shoulder the entire burden of strategic change, it nevertheless can set into motion a series of dynamics that present an important challenge to imperative control and the industrial division of labor. The more blurred the distinction between what workers know and what managers know, the more fragile and pointless any traditional relationships of domination and subordination between them will become.”
—Shoshana Zuboff (b. 1951)
