The Buell Firebolt is designed to offer uncompromised sport performance, combining advanced frame and suspension design and the willing power of an American V-Twin engine.

Key Firebolt Upgrades for 2006
· A new transmission features a “dog ring” design for quicker shifts with less effort. New helical gears reduce transmission noise, and the oil-change interval is extended to 10,000 miles from 5,000 miles. Clutch lever effort has been reduced by 15 percent on the XB9R and by 22 percent on the XB12R. A new drive belt is more durable than the previous belt.
· A redesigned swingarm is stiffer and 0.56 pounds lighter than the previous design. The swingarm continues to also function as the oil reservoir, and the oil cap has been relocated and redesigned for easier access and opening. The inner fender and upper and lower belt guards have been restyled.
· The engine air intake has been integrated with a wrap-around fuel cap cowling in the airbox cover, replacing the air duct that formerly passed through the frame. This change also enabled increased fuel capacity.
· A durable new Goodyear Hibrex 135-tooth final drive belt with Flexten Plus technology requires no scheduled service or replacement.

Performance Through Technology
The Firebolt is designed around the Buell Trilogy of Technology design philosophy: frame rigidity, mass centralization and low unsprung weight. The massive, rigid aluminum frame doubles as a 3.8-gallon fuel cell, which helps lower the center of gravity and centralize mass. For the same reason, engine oil is stored in the aluminum swingarm, and the muffler is located below the engine. The Buell Zero Torsional Load (ZTL) front braking system mounts a single 375mm rotor near the wheel rim, gripped by a six-piston caliper. Braking forces are transmitted directly from the rim to the rotor, so torsional load through the spokes is virtually eliminated. This permits the use of a very lightweight wheel that also helps reduce steering inertia. ZTL and lightweight belt final drive contribute to a significant reduction in unsprung weight.

In many riding conditions, torque and a wide power band are often more functional than peak horsepower. The Buell Thunderstorm V-Twin engine delivers torque by the bucket-load. This 45-degree, air/oil/fan-cooled powertrain is also compact and narrow in profile. Buell DDFI II fuel injection delivers crisp throttle response in any riding situation. The Buell Uniplanar engine mounting system reduces vibration to the rider and enhances rigidity by incorporating the engine as a stressed member of the chassis.

The Firebolt wheelbase is just 52 inches and rake is a radical 21 degrees, with 83mm of trail, an aggressive chassis geometry that’s quick, but never twitchy. A Showa rear shock and 43mm Showa upside-down fork are fully adjustable for pre-load, compression and rebound damping. Low handlebars and rear-set pegs put the rider in a sporting position behind a compact fairing.

Buell Firebolt XB12R
The synthesis of brute power and track-tuned agility, the Firebolt XB12R puts 103 horsepower and 84 ft. lbs. of torque in its rider’s hand. The Buell InterActive Exhaust system utilizes a valve in the dualchamber muffler that is controlled by the ECM and adjusts exhaust flow according to riding conditions to smooth torque delivery and optimize engine power. It is available in Midnight Black, Racing Red or Thrust Blue with stunning Translucent Amber wheels and Graphite Gray frame.
