Buell XB12R Buell Firebolt XB12R

Buell Firebolt Enhanced For 2006 - New Swingarm and Transmission for unique Sportfighter

The performance of Buell's radical sportfighter motorcycle, the Buell Firebolt XB12R, is further enhanced for 2006 with the introduction of a new swingarm design and a new, even smoother-shifting transmission. 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 16,000 kilometres from 8,000 kilometres. Clutch lever effort has been reduced by 22 percent.
  • The redesigned swingarm is stiffer and 0.25kg 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 increases fuel capacity to 14.5 litres.
  • A durable new Goodyear Hibrex 135-tooth final drive belt with Flexten Plus technology.
  • Performance Through Technology;

    The Firebolt is designed around the Buell Trilogy of Technology design philosophy:

    frame rigidity, mass centralisation and low unsprung weight. The massive, rigid aluminium frame doubles as a 14.5 litre fuel cell, which helps lower the center of gravity and centralise mass.

    For the same reason, engine oil is stored in the aluminium 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 acting on the rest of the wheel 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 bucketload.

    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 1320 mm and rake is a radical 21 degrees, with 84 mm of trail, an aggressive chassis geometry that's quick, but never twitchy. A Showa rear shock and 43 mm 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.

    The synthesis of brute power and track-tuned agility, the Firebolt XB12R puts 100 horsepower and 81 ft. lbs./110 Nm of torque in its rider's hand. The Buell InterActive Exhaust system utilises a valve in the dual-chamber muffler that is controlled by the ECM and adjusts exhaust flow according to riding conditions to smooth torque delivery and optimise engine power. It is available in Midnight Black, Racing Red or Thrust Blue with stunning Translucent Amber wheels and Graphite Grey frame.
