Buell

The Buell XR9R Firebolt is the latest creation from Erik Buell’s innovative design stable. This Harley-Davidson powered beast boasts a short and lightweight chassis that conceals several groundbreaking features.

The unique hollow aluminium twin-spar frame not only serves as the fuel tank, but also saves precious space and weight, allowing the Firebolt to tip the scales at a mere 175kg (3861b) dry weight. The ultra-short wheelbase of just 1320mm (52in) only adds to its agility.

The Harley-based engine, a 45 V-twin, may employ outdated technologies such as air-cooling and pushrod overhead valve actuation, but it’s paired with an advanced fuel-injection system that ensures exceptional power and drivability while meeting stringent emissions regulations.

Riding the Firebolt is an exhilarating experience, with its well-damped suspension, powerful front brake, and smooth engine delivery making it a joy to carve through twisties. The result is a motorcycle that’s both agile and effortless to handle.

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.
