The Buell XB9R Firebolt is reborn for 2004 with a slew of refinements that hone its razor-sharp edge in the Sportfighter category.
With a chassis that responds instantly to rider input and the potent XB984 V-Twin engine delivering a smooth, torquey powerband, this bike was designed to dominate the twisty backroads and sweeping mountain byways that challenge even the most seasoned riders.
The Firebolt’s innovative design is built around the Buell Trilogy of Tech: frame rigidity, mass centralization, and minimal unsprung weight. The rigid aluminum frame, which also serves as a fuel tank, carries fuel within its structure to lower the center of gravity. The Uniplanar engine mounting system reduces vibration and incorporates the engine as a stressed member of the chassis.
The massive aluminum swingarm further enhances stiffness, while minimizing unsprung weight keeps wheels in contact with pavement and reduces steering effort. Buell’s Zero Torsional Load braking system eliminates torsional load to the front wheel, allowing for a lightweight design that complements the bike’s agile handling.
And yet, all these innovations come together to create an experience that is anything but overwhelming: instead, they conspire to deliver a thrilling ride that is both manageable and exhilarating.
