Buell Lightning XB12S

2008 Buell Lightening XB12S

Engine and EFI Enhancements Boost all 2008 Lightning® Models

The Buell® Lightning® series is a family of motorcycles with a strong strain of Streetfighter DNA. Packing a one-two combination of V-Twin muscle and innovative engineering, the Lightning is a motorcycle designed to excel in the real world, where torque trumps horsepower and credibility is earned on the streets and backroads.

Wide, flat handlebars and athletic ergonomics put the Lightning rider in control of any situation. A broad, V-Twin powerband means thrust is always just a twist of the throttle away. A short wheelbase and stiff chassis – the pure application of the Buell Trilogy of Technology philosophy – produce a motorcycle that is agile and intuitively responsive to rider input. There are five Buell Lightning models for 2008.

The Lightning family will also benefit from a newly developed Thunderstorm™ V-Twin powertrain in 2008, with significant enhancements to boost engine performance and reduce required maintenance. Two versions of the engine are offered, both featuring electronic fuel injection and dry-sump oiling.

For 2008, the Thunderstorm engine displaces 1203cc and produces 94 horsepower (70kW) at 6800 rpm and 77 ft. lbs. / 104 Nm of torque at 6500 rpm. With an increase in maximum revs to 7100 rpm this gives the engine an even broader powerband, and riders the ability to accelerate longer through the gears. The Thunderstorm 984 displaces 984cc and produces 80 horsepower (60kW) at 7500 rpm and 58 ft. lbs. / 79Nm of torque at 4500 rpm. Both powertrains are tuned to deliver a broad, flat torque curve that makes abundant power available to the rider at almost any speed. In turn this reduces the need for downshifting and provides strong acceleration throughout the rev range.

What’s New on Lightning® for 2008
Updates to both the 1203 Thunderstorm™ V-Twin and 984 Thunderstorm V-Twin engine both enhance performance and reduce maintenance cost.

Each Lightning model is pre-wired for the easy installation of accessory heated hand grips, with 18 peak watts per side and High and Low heat settings.

The instrument panel styling is refreshed and the tachometer reflects the new 7100-rpm redline on models equipped with the 1203 Thunderstorm engine.

To commemorate Buell Motorcycle Company’s 25th Anniversary, a graphic with Erik Buell’s signature is placed on the handlebar clamp.

Cosmetic frame protectors help reduce damage to the frame in case of a tip-over incident.

Lightning® Motorcycles in detail

Buell do not believe in a one size fits all policy, which is why the Company offers 3 size options of the XB12S Lightning model to suit riders of all heights.

A direct descendent of the notorious 1996 Buell S1 Lightning, the XB12S is ready to unleash any rider’s inner hooligan nature. The tyre-twisting torque of a Thunderstorm 1203 V-Twin is paired with the athletic reflexes of the Buell Intuitive Response Chassis™ (IRC), a combination of throttle response, handling and sexy naked styling that is simply irresistible.
