The Buell 1125R represents an all-new platform from the Buell Motorcycle Company that is changed in almost every respect from previous Buell models, but stays true to Buell’s design and engineering philosophies. Although some of these ideas go against the conventional wisdom of the category, their steadfast application results in a motorcycle that delivers outstanding power, handling, comfort and convenience; a motorcycle that will deliver an exceptional rider experience. The Buell 1125R joins the XB and Blast as a third and distinct Buell motorcycle platform. he three legs of the Trilogy of Technology underpin every aspect of design at Buell Motorcycle Company: Mass Centralization, Low Unsprung Weight and Chassis Rigidity. The goal is always to create a motorcycle that handles intuitively, and that predictably and accurately responds to input so that the bike behaves as an extension of the rider. Here are some examples of the Trilogy of Tech as applied to the new Buell 1125R: Mass Centralization and achieving the optimal center of gravity makes quick direction changes seem effortless. Compact 72-degree DOHC V-Twin engine places more engine mass along the centerline of the motorcycle, and allows the engine to be located further forward in the frame. Massive aluminum frame spars double as a 21.2 L (5.6-gallon U.S) fuel reservoir, to carry fuel lower on the chassis. Radiators are mounted longitudinally between the front wheel and the frame. This radiator location also allows the engine to be positioned further forward in the frame. The muffler is located below the engine, rather than high and behind the rider. Chassis Rigidity allows the motorcycle to hold a precise line when it is subjected to side-loads in corners. A new-generation Intuitive Response Chassis (IRC) is optimized for torsional stiffness. The engine is solid-mounted to the frame and acts as a structural member. The swingarm pivot point is located in the engine case structure, creating a more-rigid connection between the front and rear wheels. First OEM spec 47 mm inverted front forks with reduced friction seals are secured in rigid triple clamps. Low Unsprung Weight enhances traction, maneuverability and stability. New Buell ZTL2 front brake system, utilizing a single disc and new cast caliper assembly with four pads, is approximately six pounds lighter than twin disc brakes. The New Buell ZTL2 front brake transmits forces from the rotor directly to the rim, so torsional load acting on the rest of the wheel is virtually eliminated. This permits the use of a very lightweight front wheel hub and spoke configuration that reduces steering inertia. The rear brake caliper is mounted directly to the swing arm eliminating the typical brake carrier and an additional 1.5 pounds of unsprung weight. A reinforced Goodyear Hibrex final drive belt with Flexten Plus technology weighs just 1.06 pounds, compared to drive chains that weigh four to five pounds.
